How good (or bad) is the Trinity

OK I see that some of you already got the device. My wife wants to replace her Nokia N80 for the white version. Now I previously had an Orange SPV M3100 (HTC Hermes) & had no end of problems with that sold it & now happily using an Asus P525. So how about the the Trinity.
-Is it stable?
-Does A2DP & AVCRP work properly as in having proper stereo output?
-Does the A2DP reconnect automatically to WMP after receiving a call (the -Hermes never did, had to restart everything).
-How's wifi reception (the Hermes was crap). She uses wifi a lot as we have 250mins free BTOpenzone minutes a month.
-I looked at the HTC website but it seems they do not supply firmware upgrade support for their devices. So where can you get them officially?
Fill me in guys. Thanks

Is it stable?
I don't feel it's very stable when coming to the phone part. If I've used the device for a while, I often have to hard-reboot it for the phone part to work again(it just stands "calling", and nothing happends)
-How's wifi reception (the Hermes was crap). She uses wifi a lot as we have 250mins free BTOpenzone minutes a month.
The WiFI reception on my phone is very good. I've actually managed to connect to hot-spots which my laptop didn't manage to connect... *me like*
-I looked at the HTC website but it seems they do not supply firmware upgrade support for their devices. So where can you get them officially?
In Norway you get the official firmware updates/rom from the local distributor.(Dangaard and Brightpoint)

What about other features, like those related to the cameras?
How is visiophony with the front camera?
How is the picture quality of the back camera? Most of the reviews are made with good light conditions. What about the pictures in low light condition?
Movies? Are they correct?
Battery life with that 400 MHz processor compared to Prophet?
Could anyone post pictures/movies made with Trinity?

The wifes P3600 arrived this morning. Been playing with it all for a while & here's my 1st impressions.
Good
Looks nice & shiny
Small size
Excellent loud clear external speaker
Nice & responsive
Phone reception & general operation is fine
3G works well
Bad
Shiny surface = fingerprint magnet
MS bluetooth stack, better than before but still lacking
A2DP implementation. Not real stereo, only mono out from each channel
Also when disconnectd from WMP it doesn't auto reconnect.
In summary if you used previous HTC devices before then you'll be familiar with this one. When used as a pda & phone it does most things as expected, the menus & general operation are same as before.
But its going back, one of the main reasons being the crap A2DP. Wifey uses music player a lot on her 1 hour daily commute & the fact that sound quality is rubbish (low volume & no stereo) & no option to connect a wired headphones as theres no headphone jack. The same problem as the Hermes in that once disconnected from WMP it doesn't auto reconnect. Have to go into Bluetooth manger to re establish the connection.
Also comparing it to my Asus P525 other than the smaller size, 3G, louder external speaker & looks a bit nicer, in all other depts the Asus is as good & some areas much much better.

Well, my opinion is that the camera sucks... Was on a party this weekend _with_ good lighting, all the picutures came out blurry *argh* (could be it was too much light tough?...)
The videotelephony-part on the other hands is quite good(for videotelephone, NOT for taking still-pictures).
And I also don't like the 2-7 sec. delay when you try to call someone... *argh*

2 to 7 second delay? It sounds like a ROM upgrade will probably be coming to fix these issues...same story different cover.

This sounds new to me. I am using a SonyEricsson stereo BT thingy with my Qtek S200 (with A2DP hack) and as far as I can hear the output is stereo not mono from each channel.

I love mine compared to my Exec! Quicker and sleeker.
And got my 4GB miniSD this morning and it works fine

Yes, proper stereo could be possible with a registry hack but how many end users are to know that? Only the hardcore users frequent forums such as this & get to learn a lot about their devices. Assuming it can be done then why didn't HTC enable it in the first place? Mention a registry hack to the vast majority of users out there & I'm pretty sure you'll be met with a lot of blank expressions & ??????
With the aesthetic design of the trinity I think HTC are trying to market it to more mainstream audience, thats why my wife likes the look of it, but in all honesty how many of these new users will know how to exploit the device to the full. My wife never visits these forums & even her 8 month old Nokia N80 is still out of the box stock.

I thought the registry hack was only to enable A2DP on those devices where the manufacturer had disabled it and the end result of a hacked S200 would be the same of a standard TyTn or a standard P3600... Are you sure the P3600 output is not stereo?

Pretty sure its not stereo, either that or the stereo separation is really poor because it sounded like mon to me. In saying that though when I paired my iTech R35 stereo bluetooth clip with it there was the option to tick headset mode & stereo mode but its too late now I've sent it back today.

The only dislike on my new P3600 is the position of penon the bottom! . I've used many pda, and the pen was on top! But for the rest I love it!!!!

You are right the stereo bluetooth output is not stereo. This is ridiculous. I hope this can be fixed with some registry hacking otherwise HTC has really screwed this device big time.

One more thing, the smooth black coating is comming of from the bottom where the stylus is placed.... That's s REAL bad thing, since this will eventually tear up more and more of the coating... And I've only had it for two weeks

default A2DP registry settings for Trinity is:
UseJointStereo = 1
please change to:
UseJointStereo = 0
that will fix the "mono sound" issue.

Question
So far what i read, the software for this phone 3600 is not fully stable,
Camera still delay..
Some bugs
additional question following,
Delay of standard programs opening?
How about the sounds quality (loudness and clearness) is it very good?
which one is really better if compare 3600 and 3300(GPS enabled), which should i buy... -_-"
Thank you in advance..

fantastic device
Got my Trinity since yesterday. I had several phones and pda before (Dell Axim x51v was the last one) but the Trinity is the best until now. small enough, fast enough... if I only could get MMS to work for vodafone germany...

Did you try these (manual entry and cab for Vodafone):
https://shop.dangaard.de/files/Qtek/Qtek.htm
Tytn and Trinity 3G/UMTS should be the same

So far...the trinity is my new favorite thing..very stable (have had to soft reset twice to get the Wifi signal running after a sync while wifi was on) and lots of fun. Phone is great and signal with one bar or less is still usable - where my old motorola was no good with a weak signal...and i can now make and take calls from my office - where previously there was no chance with the motorola. This device does everything I bought it for -combine my PDA and phone into one device...

Yikes! I just fixed my A2DP skipping problem with this patch!

Background:
When jompao (his original thread on this is here) brought an interesting A2DP workaround to light I was intrigued:
Apparently there's this free, opensource taskmanager which, when running, corrects the Hermes skipping problem! So I tried it for myself and damn if it wasn't true! Not only did it allow my iPAQ stereo headset to operate w/o skipping but the non skip range on my HS-12W was doubled too!
So, I obtained the code and found out what was going on. Turns out, this free little gem of a task manager determines CPU usage by running an infinite loop thread (it does a "while(1)" for all you code jocks) at THREAD_PRIORITY_IDLE, then, based on a timer trigger, it periodically stops the thread and sees how much time it got. The more time it gets, the more idle the cpu being the rationale here.
btw: Thanks for generously donating your Taskmanger to the opensource community Yuichiro Ishitani!
Anyway, I said to myself "Heck Sleuth, you can build a service process that does this in about 5 minutes". So I did & now I listening to skip-free Jimmy Buffett on my iPAQ headset with my little A2DP fix service running in the background.
heheheheh.....
Installation Instructions
1. Transfer A2DPFix.cab from the attachment to your Hermes device
2. Tap on the cab to install. Note: you must install this to your device! The service dll can't run from extrom or your storage card!
3. When the installation is complete, reset your Hermes
4. Enjoy skip free A2DP!
Early implementor additional instructions
I had to change the service key to allow automatic start so you will need to manually remove the old key. You must do this before installing v1.0. Here's how:
1. Stop the A2DPFix service
2. Remove the entire HKLM/Services/A2DPFix key from your registry.
Latest Breaking News:
12/03/06
There may be registry settings, previously done in an attempt to work around the skipping problem, that are now hindering rather than helping. Changing quality and other A2DP settings with the Hermes registry Tweaker may actually contribute to this. If you are still skipping with a known good ROM/headset combination, please check your registry settings against these and report on your findings!
(all DWORD values are decimal)
/HKLM/Drivers/BuiltIn/BtA2dpSnd
remove any Priority256 value
HKLM/Drivers/BuiltIn/WaveDev,
Priority256=149
/HKLM/Software/Microsoft/Bluetooth/AudioGateway
Capability=37
/HKLM/Software/Microsoft/Bluetooth/A2DP/Settings
UseJointStereo=0
BitPool=58
MaxSupportedBitPool=80
Remove all other values from this key including SampleRate
Don't forget to reset your Hermes if you change any of these!
12/02/06
As promised, there's now a CAB based installation
ROM version dependency confirmed! This patch's effectiveness is inconsistent with the orignal v1.18 TyTN ROM. YMMV on this ROM for sure.
12/01/06
The success of this patch may also be related to the ROM version you're running. I have the latest TyTN ROM loaded and it has quite a few out-of-the-box performance tweaks which are also included in the latest Cingular and DoPod ROMS.
Known Good ROMs/Headsets
These ROMs are known to benefit from applying this patch:
TyTN v1.35 ROM
Cingular v1.34 ROM
In addition to the few headsets that used to work, the following additional Headsets now work with this patch (I'll add more as I find out)
SE HBH-DS970
Moto HT820
Logitech iPod Headset
HP iPAQ Headset
Jabra BT 620S
As always, Enjoy!

Tried it according to your instructions (imported the .reg with Total Commander), started BT and set my headset as Wireless Stereo (for some reason the TyTN doesn't keep the setting even when selected in the partnership settings.
And it still skips (drops audio) for me.

Is the service started? What A2DP headset are you using? Did you try the Taskmanager workaround I referenced, and if so did that work for you or not?

Yes, checked with dotFred's TaskMgr. It autostarts after a soft reset it seems?

It will auto-start only if you're also running SPB Pocket plus.
edit:
I'm trying a reset now to see if it's still working afterward....
edit2:
Still working for me. Set your following registry entries to the following and see what happens:
HKLM/Software/Microsoft/Bluetooth/A2DP/Settings
UseJointStereo = 0

Done, still skipping. Although it looks like it's skipping a little bit less now. Also, the TyTN is completely unusable when music is playing, it is VERY slow to respond to anything other then the pause/stop and forward/backward buttons on my headset.
ROM version: 1.18.255.3
ROM date: 07/22/06
Radio version: 1.03.03.10
Protocol version: 32.34.7010.01H
ExtROM version: 1.18.255.106

Yeah, that's normal with your ROM. You're on an original TyTN ROM. You'll even lose the digitizer occasionally with A2DP running. I wonder if this patch is ineffective on your ROM. I'm using the South African v1.35 TyTN ROM currently.
Edit:
Did you try the Taskmanager workaround? I'm betting that won't work for you either. Part of this patch's requirements may be upgrading to either the latest Cingular, DoPod or TyTN ROM. These ROMs have a quite a few performance tweaks that may just allow my A2DP patch to "take it over the top" from a skipping perspective.
What BT headset are you using btw?

Yeah, I know what you mean... I'm getting used to the routine now tho but it still takes a while. Flashing itself is less stressful now that I have a known good computer with a known good USB port which I use for flashing. The 20 minute Hermes flash process caused high anxiety for sure the first time I tried it.

guess I will bite the bullet tomorrow and upgrade, It's 2am here and that's not a good time to do anything that stressful.
Have any good links for upgrading?

Not really. Here's some tips though:
Practice safe flashing techniques:
1. Windows XP with nothing else running
2. Screen saver off, sleep mode off, powersave mode off
3. Use a rear USB port. Make sure activesync works ok on it.
Do pof's SuperCID upgrade first. See his thread in the upgrading section for how. There's good step-by-step instructions. I'd read through the whole thread (takes a while) first to be familiar with any pitfalls.
The current TyTN ROM can be found in the Wiki along with flashing techniques and recovery for common errors.
and finally: don't exit until the ride comes to a complete stop....

Excuse me but I'm fairly new to Tytn and Windows Mobile devices. The .zip file should it be renamed to .cab once downloaded or is this something you will upload later?

Thanks Sleuth! Upgraded and now I have no more skipping audio!

@jompao:
Sorry about this reply's delay: it's now morning here in the US Midwest. If you unzip the archive on your PC you'll find two files: the reg file and the dll itself. It's strictly for "early implementors" though so if you don't know what to do with these offhand, just wait a few hours and I'll have a full install cab posted. I have to code up a small program to start the dll automatically first.
@Hiryu: that's great to hear I'll add your jabra headset to the list of supported hardware. Btw: did the upgrade correct the problem that headset has with pairing or do you still have to go into bluetooth settings to get it to pair?

A big mahalo to you Sleuth!
Works great on the HTC v1.35 ROM to a pair of NBH-DS970's... one little skip while downloading over UMTS but fixed that by pumping up file caching to 4mb and audio buffer to 2000 msec on pocketplayer v3.01. No slowness whatsoever.
Email, internet, open and closing various programs all while jammin' to a little jeff beck's guitar shop...

x7500 - Jabra 8010: voice disruptions/discontinuance reported by people I talk to

Hi guys,
I am wondering about the happiness of the union X7500 - Jabra 8010. Sometimes people I talk to tell me that they barely understand me because they hear disruptions/discontinuance in a voice coming from my side. This almost never happens for voice coming from other party. I am not saying the "couple" is responsible for this but it gets me thinking... What could be the reason for this? Why voice is not corrupted in both direction (up&downlinK)? Ohh, I have the BT configured to Stereo, but I think there is no difference in case of mono…
Is there any way I could test the voice quality coming from/to Jabra? Resco Audio Recorder? Anything else….?

jabra 8010 promblem with athena
i have the same problem.

This problem not only happens with my Jabra BT8010, but also with my other bluetooth headset i.Tech Clip D.

I have the same problem too, but not always happen this. Sometimes the quality is good, sometimes bad. If the headset properties on Athena is hands free the outcoming voice is clear. If you're connecting the Jabra with Athena and there aren't any stereo icon on taskbar coming up, the problem dont ocure.
I have WM5 on athena. Perhaps WM6 will solve this bug (Or a new Jabra update).
I tried it with another phones and it worked good.

Hi!
I have contacted HTC support for this and just received their reply. Man, they are "really quick" - 2.5hours - for the bullsh#!#t answer they provided...
Her is the reply:
"Good morning
We are very sorry to hear you are having problems with Bluetooth. You may find that Windows Mobile 6 may cure this problem when it is released for your device on the HTC eClub.
For now we would recommend using a compatible recommended Bluetooth headset as below:
http://www.expansys.com/htc/p_htc_item.aspx?i=150737
Thank you for your enquiry, Should you have any other problem, please do not hesitate to call us. Your Local number can be found at http://www.europe.htc.com/support/csbyphone.html
"
I shall install Resco Audio Rec and try to record one of these problematic calls. Maybe it will make a difference presenting direct "evidence"...
Any other ideas?

I've got an X7501 Advantage with WM6 on it. I'll be getting the BT8010 in a week or so. I could test this out if that would help.

I have X7500 WM6 Jabra BT8010.
It just disconnects at random times. I will go back to my Jabra BT500 and use the BT8010 only when I want stereo music or other audio output.
Hopefully Jabra will take a look at this problem.

Bluetooth priority patch?
Just curious, have you guys tried installing the Bluetooth priority patch?
http://forum.xda-developers.com/showthread.php?t=262119
I believe it increases the priority given CPU wise for the bluetooth audio. It actually resolved a problem I was having with my BT8010 and the Universal, the audio during a call was a little choppy and callers reported that my voice was frequently dropping out no matter how close the device and headset were. After downloading and installing the registry edit in the 1st post of the thread I linked to above, problem is gone.
Please let me know if this works, I'm considering purchasing an Advantage and would want to know if it works with my Jabra BT8010.
Thanks,
Galt

hi guys
i've got the same problem.
but not only when using my jabra bt250v
but also when using the wired headset, or no headset at all
so imho this is not a bluetooth related problem
after installing wm6 the problem didn't improve at all.
HTC produce the best WM devices out there
and the Advantage is their flagship device.
These problems with the most basic function shouldn't happen.
And HTC's answer is just poor!
I'm sure they know about this problem and also know that WM6 doen't fix it
(or at least not the ROMs available until today).
I'm still waiting for another RadioROM to fix this fault.

hi galt,
Thanks for your post. I have manually entered the fix form your link:
"Make a new Dword value and name is Priority256 and then for the DWORD Data value make that 60 save and reboot. Presto no more lag, cuts or audio drop outs." since the attached reg file did not have the contents the author has been talking about. I made this reg file with a fix and would like to share with you...
I will test it and let you know how it goes...
Uros

Could someone monitor battery consumption with this fix?
There was a similar fix with A2DP and the current consumption was crazy, so I uninstalled it...

Good news so far
1. With the fix installed and the X7500 "at rest", there is no additional current drain = 90 mA.
2. With BT on playing music throught the Jabra BT8010 the current drain is about normal = 320 mA.
3. With BT off, the current drain returns to normal "at rest" current of 90 mA. With A2DPfix the current drain remainded at 400+ mA.
Good news so far!
NOW: the remaining question: Does it solve the problem of dropout?
I'll try it for a day or so and report back.

GREAT news so far
After 4 hours of listening to music (X7500 WM6 BT8010) with Priority256 installed, I can report:
1. One BT dropout that lasted less than 1 second!
2. Normal battery drain!
I have not used the phone enough to know if there will be and BT disconnects or voice issues, but I will report back on these issues soon.
Looks very good at this point.

So far so good
Hi,
It worked for me as well . Almost completely gone, except some tiny/small discontinuance from time to time... GREAT!

I've been using this fix for 3 days and so far having no complain from the people I talked to. Good fix indeed.

Thanks for posting the zip file, makes installation painless. Testing right now!
Well, so far so good. I did experience 2 or 3 drop outs during music play, but I can not contribute them to the device as I was in my office and an ambulance put on their sirens, somehow there must of been some interference.
The best thing about music play was that when the player switched to each successive song, there used to be an audible click or bump, that just isn't there now!

Did anyone ever confirm if this fixes outgoing audio problems? I've had several callers complain of noise/breakups coming from me, when they sounded normal. I know it wasn't a signal issue since this happens when the Advantage is next to me, and I've used my 8010 from 50 feet away through multiple cube walls plus one real wall...

Try to upgrade your Radio ROM to v1.50. That'll solve most of your bluetooth problems.

Extrem System Slowdown Using A2DP

Hi
I am Using Schaps WinMob6 with an Motorola S9 over A2DP, as soon as I start streaming the system slows down so bad that it is almost impossible to use!
Is this normal? Anyone using A2DP experiencing the same Problem? What can I do to fix this?
Grüsse,
Chris

i have experienced the same thing no matter when ROM I use. theres not a lot of settings to change so they just sit in a drawer now collecting dust.

i have experienced the same thing no matter what ROM I use. theres not a lot of settings to change so they just sit in a drawer now collecting dust.

I'm experiencing this as well with Schaps ROM. If someone got it to work without problem, please let us know.

Hmm, I don't remember this problem when I was using Schaps ROM... what app are you using to stream. I pretty much solely used Coreplayer 1.1.1 for everything though.
Definitely not having this problem with K's rom which I'm testing now. It works sweet.

If I remember correctly I tried with both WMP and PP with the same result.

I believe A2DP takes a fair amount of CPU power - first the application needs to decode the mp3, then feeds it into the virtual sound device - bluetooth stereo - whose drivers then transcode the sound into something that can fit into Bluetooth's bandwidth. The transcoding has to be done in real-time so it probably has a high priority for CPU time. I don't think I've ever used a ROM where A2DP wouldn't slow down the device, and this includes an Axim x50v @ 624 MHz.

Hi Guys,
I have the feeling that things have gotten a bit better after installing Total Commander!?
Does this make sense?
Using TCPMP with You Tub plugin ( Vids Run great unless A2DP / )

It IS processor-intensive, particularly on Samsung CPU's, where it can easily eat 50% CPU time. This is why there's so bad a slowdown.
Read my related articles, they're all cross-posted to the Wiki here - I've elaborated a LOT on all these subjects.

mortplayer seems best for me, but yes there's always slowdown, the tcpmp thing; its the only program with which you can watch videos cleanly without skipping/slowdown via a2dp.

Darn
I just upgradet from a Magician in the hope that the Samsung would have more Power, but / On my Magician ther ist almost no Slowdown using A2DP.
Are there any aps where I can OC my Samsung?
Sadly My tcpmp skips vids using A2DP . I guess I will only be using my S9 when Joging or Biking.

I'm having these probs on my 8525. No clue how to fix it. Theres a lot of storage and program memmory left on the darn phone. It used to work perfect, but suddenly had problems. The music stutters a lot with both wmp and tcpmp. I'm using the iphono minis with A2DP. These issues never existed with WM5 as far as I know, though the quality was of course lower. Perhaps the processes that up the quality of the [email protected] stream are causing a trade of in CPU/memory consumption. Maybe that means lowering the quality (maybe via a registry tweak) somewhat will alleviate the problem?

I'd recommend switching to a wired headset
I got the same issue with my A2DP headset. It's not an issue that can be fixed with tweaking. A2DP is simply CPU intensive (not memory intensive).
Lowering the bitrate would help, but not enough I'm afraid.

tweaks that help
Hey there,
I had a little trouble with helmi's wm6 (excellent rom) and the original wm5. The following link has some reg tweaks (http://forum.ppcgeeks.com/showthread.php?t=10668). It's still a little gappy, but much better. Also, the sound quality seems to be a lot better.

Improve sound quality via BT A2DP

Does anybody know how to improve sound quality for playing music over A2DP profile with Parrot handsfree? On Rhodium i applied some tweaks for quality improve and it was clear and nice to listen, but Leo is not so nice to hear
Thx a lot

I had to tweak my diamond too, looked for tweaks on the HD2 but couldnt find them, but the sound quality is way better on my HD2. I dont think it needs the tweeks tbh.

If i take both, TP2 and HD2 to my car, let play the same song and im switching between HTC's then has got TP2 much more clear and brilliant sound, without any quiet cracklings from tweeter speaker like it is on HD2 :-(

Same problem here, sound quality for a2dp is not what it should be. I tried adding the LineSpeed registry setting, it did improve the overall quality, but did not remove the cracking noise - and in my case I still have frequent skipping and gaps in the audio playback. Have not yet had a reply for Tech Support, and if/when I do, I don't think it'll be a very intelligable one...

Yop, i think too, that the answer will be unusable, or maybe they tell you that u should do a Hard rst :-D
First time i connected it to HF and let music play i thought that is a bad quality song, but it isn't :-(
Anyone idea?

I know there are some settings to definately improve the sound of A2DP. I've added them on my previous HD, and worked perfectly after that! I just found some things you might try (I just applied them myself as well, but havent tested them yet; I'm almost sure they'll work):

If I'll find the previost post which I applied in the past on my HD, I'll let you know. If the one I just posted will work, I'll let you know as well of course, because the litteral and figural crappy sound of A2DP is something I hate as well...
Edit:
Take a look at those settings as well from J-A-J-O at page 6:

Again, I don't know exactly if it were those settings, but they sound familiar to me. I'm also busy trying to get the best sound quality via bluetooth out of my HD2

The XDA tweaks are rubbish and do not work. I currently have a call out with HTC.
I have removed all reg tweaks from my HTC and now can get A2DP working on my parrot ONLY in the following situation:-
(1) Reboot HD2 (hold end key and select off. then switch on)
(2) Allow to connect to Parrott (will connect handsfree first)
(3) Open bluetooth from settings and select stereo audio and select connect.
(4) select handsfree and select disconnect.
(5) Press PLAY on the parrott kit
By doing this I get no skipping at all and the quality is good. I have no tweaks running.
This is obv crap and is why I have been speaking to HTC all week.
Steps 1-5 have to be strictly followed for this to work.
The BT tweaks mentioned on this forum do not work. They only appear to work as you have rebooted. After using the HD2 for a while and then connecting A2DP, skipping will occur again.
Try steps above and it will work.

Interesting! I'll try that on mine. Greenfrog all of those links and bitpool settings relate to the Microsoft Bluetooth stack. However the HD2 uses the Widcomm stack so those registry settings can't be made.
I too am fed up of the bluetooth sound quality. How can they assume we'll be happy with this mediocre sound?! I can't see why with a 1Ghz processor it skips.
Have you guys tried the A2DP with the latest 1.61 ROM? I'm still on 1.43....
When I find my 'goldcard' that I made I'll try it on 1.61 and let you know
We'll get there in the end....this is really my only bugbear with the HD2, so it would be good to get it fixed!!!

There got to be a way!
I, too, am really p***ed off by the bad audio quality i get using stereo blutooth. It's really an issue with the HTC HD2 and apparently no pro reviews pointed it out!!! I use it with the sony DR-50 which are one the best A2DP headphones out there, but the sound is horrible Please help...

I'm too suffering from the A2DP situation...
The Linespeed registry hack helps me on some devices ( HKML\Software\Widcomm\Plugins\AV add DWORD Linespeed with value between 64 and 512, the higher the better sound but higher probabilty for skipping).
With Linespeed = 320 sound is great and I have no skipping with a Sony DR-BT160AS. But: My Motorola S9 badly skips unless I have it very close to the HD2. Linespeed = 256 is working ok with both devices...
BUT:
I also have a blueLino A2DP Receiver which has a bad quality on both settings, at least on some songs. That's really disturbing.

Just a quick update, I've just flashed to 1.61 and it makes no difference. Default A2DP sound quality is unacceptable. Grr

Well, first I have to say I don't have the 'skipping' issue at all. I have my HD2 connected via bluetooth to my Pioneer DEH-P7100BT car radio. I have a clear connection when calling, but when playing music via bluetooth, I have the 'hissing' issue.
Next is that I have to admit that when I changed the settings according to my previous solution, did work a little, but not as it supposed to. When I had my previous Touch HD if found a link which worked perferctly for me! When I changed to those settings, the hissing were gone completely and the sound quality improved to CD level. Although, I'm still searching those ones again for my HD2 at the moment....
So, conclusion this far is that it totally depends on the hardware which you are connected to as well.

@Greenfrog:
I guess the bitpool settings which worked well on my HD as well, only work when using the MS Bluetooth stack. The HD2 uses the WIDCOMM Bluetooth stack, I haven't found a noticable difference.
The LineSpeed registry setting does improve overall audio quality, but I still have skipping and playback gaps. Very poor performance for the performance beast the HD2 is. I urge everyone to report this to HTC (I did) - this is really unacceptable.

I will also report this to HTC. I am so frustrated by it tbh

As Moses posted...I had linespeed set up on my TP2 and the sound was great, but now i have no time to test it now, can someone other test regitry key?
Bluetooth settings
Can be found here HKLM\Software\WIDCOMM\
A2DP Tweak Provided by R_phAn (Please note this will not work with all devices)
As we know from the past, each device has it's own preferences and capabilities (So you'll have to play around)
Managed to improve soundquality by adding DWORD 'LineSpeed' to HKLM\Software\WIDCOMM\Plugin\AV\ with a value of 320.
it is posted here for TouchPro2: http://forum.xda-developers.com/showthread.php?t=524655
Edit: I tryied it tomorrow morning and it is still the horrible quality, poor music quality and during the call skipping :-/

Okay, thanks a lot for this update! I was really unaware about the different stack, so I don't have to look further for the the previous links anymore... I'll try to add linespeed as well to see if it works with my Pioneer car radio. I hope it will...
There should be an answer for sure for this issue. I also cannot understand why it have to be this difficult. The previous solution did work very well. Why have they changed to the other stack anyway? Does someone know that?
I'm running the 1.48 ROM btw.

I found one thing, i'm using SPB Radio for online streaming, when im listening in my car streamed radio then the sound quality is excelent...? How is that possible?

That's a very good question.
I experimented a bit with different quality settings during mp3 encoding. I found out that there indeed is a connection between the quality settings of the mp3 file and the badness of the sound quality, at least to a specific degree.
The most important setting seemed to be the stereo setting. If I set a song to "Joint Stereo" its by far better than normal stereo, although not perfect, yet. That's very confusing.
Do you know the settings of the radio channels you can stream with good quality? Maybe that would be worth a test.

--Update--
So I had a predictably useless response from HTC. Namely 'have you tried unpairing and repairing' and 'your device may not be fully compatible, please check our website for a list of compatible devices'.
Useless indeed. Their compatible devices amount to 3 items! The phone is either A2DP or it isn't. There are no compatibility options - it's happening to us all.
So, I haven't mustered up the energy to continue onto the next pointless exchange of basic trial and error possibilities. No doubt their next reply will be "have you tried rebooting the phone"...
Anyway, I digress. I noticed something today. I put on a new album to my SD card and out of nowhere the skipping was worse than ever. Audiomanager is always on the lookout for new songs as you may have realised. When you have music playing, a small circle rotates to show the player is searching. During searches whether or not you've introduced new mp3's to your device, it always makes the skipping far worse. When my circle had come to a stop, then the audio was fine....with very rare pauses and skips.
Still there but much less obvious.
Well that's my latest update and I will continue my investigation. I wonder if this skipping occurs in other music programs? ie wmp or pocket player? Has anyone tried?

Great work, guys. Nice to see a lot of people looking for a solution. I REALLY want to get this A2DP thing working right, it is bugging me a lot, and I'd like it to be fixed when I'm going on vacation (I'll be driving to two straight days, and would love to listen to my own music then). That'll be in about six weeks, so there's still some time left.
I'll try SPB radio myself, see if that causes the same amount of skipping. It could be that it is not the BT link causing the skipping and pauzes, but the audiomanager itself. That would be a bummer, because fixing that is probably way beyond what we can do here, and we'll have to hope for a HTC fix or a custom rom with an older and better working version of the audiomanager.
In my search for possible solutions, I found the priority of the A2DP can be altered. I've added the reg Dword value "Priority256" to HKLM/Drivers/BuiltIn/BtA2dpSnd, with different values. If the value is too high (150+), nothing changes. Set it too low - I tried 60 - and BlueTooth fails to start altogether. I've now set it 149, and it seemed to work, but haven't done extensive testing to see if the skips/pauzes don't return. Will get back on that.

I've tried PocketMusic, qualitywise no difference. I don't remember if it had the same skipping / pauzes problem, but the problem for me was it doesn't work with the AVRCP, so I can't play/pauze/ff/rew with my remote, and having to use the screen while driving is a pain - I've mounted my device quite high. I was really hoping to use the inbuilt musicplayer
