Wizard pondering

I've started to consider a Wizard as a WM5 development unit, alongside my Magician, however, there are a couple of questionmarks that I need to straighten out first
One should never look too much at the processor speeds, but the TI OMAP 850, which runs at 200MHz doesn't sound much to the Magicians' 400MHz XScale CPU.
Does anyone have experience from both platforms? Does it "feel" sluggish?
* Audio quality / sound level
I've grown accustomed to quite a nice audio quality, but rather poor sound (phone) level on the Magician. Is this a problem with all HTC units, or is the Wizard an exception?
* Bluetooth stack
Is the A2DP profile available, or are there severe limitations as always with the MS stack? Which profiles are available btw?
* Generic performance
I read about TCPMP lately has been improved giving 100% performance on the TI OMAP 850, but how does other application stack?
I really don't use CPU intensive applications or games, but I still enjoy a fast response from the OS.
* Any minor/major issues?
Are there any kind of issues or annoyances YOU might have found?
Sorry for the lengthy post, but I feel You hacker-type guys are the only people who might help me, since the people selling these are only interested in another sale.
Thank you for your help.

I've not had an HTC phone that had decent phone quality, main issue has always been garbled voice from speaker. Compare it with say something like a mundane SE phone like a T610 or K700i and they are much more 'high fidelity' if you like for in call quality.
Wizard is slower than Magician, but things like not having to rely on backup batteries and WM5 and the ROM/RAM config is the reason. You can tweak it to run about 10-20% quicker though with a little patience. Some good 'hacks' too like accessing the extended ROM and the unlocker both kindly made by developers here.
Most 'issues' are intangible if coming straight to the device from a phone or something, only when you have been using a Blue Angel or Magician that you notice the speed. The offset is the quality feel, WM5 which I find lots better than 2003SE (not everyone agrees) the keyboard, WIFI and Bluetooth 2.
I think you can change the Bluetooth stack, best search the forums for that one.

Universal's A2DP Quality

Hi,
maybe someone can give me some info.
Have a T-Mobile Germany MDA Pro with the newest Stock ROM supporting A2DP.
Have board a brand new Plantronics Pulsar 590A Headset. It works, but the quality of the sound is very very bad with my Universal. I have also tryed the smal A2DP Sender, that comes packed with the Plantronics device and the quality is 100 times better. What is the problem? Can I adjust the bitrate of A2DP transfer in wm 5.0 registry?
The sound is a little much deep and on mid to hig frequencies, i hear a high frequencie noise.
Does anyone else has this problem?
This is not a problem of the receiving device.
Thanks for any help on this :`)

No Ideas?
Please Help!

I have the Qtek WWE ROM on my Qtek (latest official version). I use a Jabra bt620s, and i have no problems with it.
Maybe it's some obstruction of the signal? Do you encounter the problem when the Qtek is in clear view of the headset at a meter away?

I have the Motorola HT820, and finally got round to installing the Qtek WWE ROM today. Connects fine, I can walk into another room from the Uni and have no problems; But -
I also get a high pitched noise, particularly on music with lots of treble. It can be controlled up to a point by tweaking the graphic equaliser, but it is still annoying.
When using the HT820s linked to my Bluetooth PC and laptop, they sound superb - so it is a problem with the universal.

Thanks so far, i start hating my Universal ....
I think, there can be 3 reasons for that.
The Windows Mobile A2DP Software encoder, if it is software encoded.
The Bluetooth Chip, if it is HW encoded in Bluetooth.
The Radio ROM or Chip, if it is encoded on the Radio Processor.
I am not so deep in the Universal Technologie, but i know, that the sound was very clear on Blue Angel using the broadcom stack. So I think, it is M$ Bluetooth that makes the problem, but i am not realy sure.

... or is there anyone how don't has this kind of problem?

Hi,
I personally have never had that problem (which I interperate as "some form of noise" when listening to music over A2DP) you guys mention here, neither with my Motorola HT820's or i-Tech BluePRO's.
Only problems I have had with A2DP and my Universal is;
1. Pause/Resume button not working always in Windows Media Player (works fine in latest version of PocketMusic though)
2. Not automatic reconnect of A2DP when I turn headset on (only prob with the i-Tech's, Motorola's seems to work fine)
3. Occational drop/loss of sound for a second or two (have this under control now, only an issue for me now, when there is to much obstructions between Universal and my i-Tech headset)

This is a general Universal Problem. Maybe Radio Interference, maybe missing some CPU power.
The noisy and unclean sound can be a ROM Version Problem, if you don't have that. I have tryed also with a Linux Computer as A2DP SINK Client, and the sound is same bad.
That's my ROM Version Info:
ROM-Version: 1.30.113 GER
Radio-Version: 1.10.03
Protokoll-Version: 42.44.P8
ExtROM-Version: 1.30.223 GER

Try downloading the latest PocketMusic version (if free for 30 days I think...so you'll be in heaven for 30 days at least), there it works perfect. ...it was enough for me to "cough up" the money to buy it!
And yes it seems to be every second time, and then one has to press button on Universal/Media Player once...bloody irritating...when the Universal is in the bag or something.

Yepp, I have exactly same behaviour (handsfree no prob, while A2DP needs manual reconnect with iTech's...but with the Motorola HT820's I belive it was automatic though)

For me I am pretty sure it is pure radio problem now (have tested with an app called SuperTask, and A2DP takes approx 20% CPU, and my JasJar now used a total of 40-45% CPU when I listen to music over A2DP with PocketMusic). I only have this problem when I have the JasJar in my pant pockets, are in an area I know there is a lot of interference+have some obstructions. Except from that it is fine now.
You can see this post on my "socalled test" (it was just a simple test, but it seems to give a good indication at least) of A2DP's effect on CPU here;

I have no clue...do you have a Universal (I would guess so from that you post it here )...if so the HW is identical...so then...yes it should be the SW/ROM...since you actually have tried with another "headset" (your Linux computer). But I am sorry, that I am not much of contribution...if nothing else...I agree with your logic here!
BTW my ROM version++ is stated in the A2DP-test post I linked to above (don't remember the numbers...but I have the "latest QTEK WWE" ROM).

Thanks for your comments.
Maybe it's the T-Mobile Germany ROM that is the Problem. Have allready called the technical support at T-Mobile, to help.
Maybe they are ignoring me, but i have tryed.

Universal's blue tooth signal terrible
Look I had many imate devices and bluetooth sets. The Universal has a very weak bluetooth signal even with normal bluetooths.
I have tried 3 or 4 different bluetooth headsets and they all give me a max of 3 meters. With the Jam and pda2k with the same headsets I used to get 10meters.
I gues this is the reall problem you are facing, the bluetooth reception is terrible on Universal, try being really close like 40CM away and if the sound is good you will know that it is only a reception issue from the universal.

I noted the 40 ~50 cm distance problem when I reviewed my nokia hs-12w a2dp headset about a month ago, it is very irritating. I think it is to do with where the BT chip is placed !!! it is between the keyboard and the battery, from what I could tell of the exploded diagram on this site !! meaning it is surrounded by metal !!! not good .
PS I never have problems connecting my hs12w headset for audio use, however if I take a phone call, after the call has ended I loose AVRCP

Hi cr2,
yes I read about it in IRC Log. But what you like to do is, streaming sound direct to the bluetooth hardware. Universal hardware supports this feature. There are 2 Bluetooth Profiles implemented for, one is called "Handsfree" and one is calles "Headset" and ini Windows Mobile Registry you will find it if you look for "Audio Gateway". The registry values are also documented in the online MSDN Lib. I will post a link, later, if I find it.
What I am doing is A2DP, that means ... all stereo sound will be compressed in software and then send as datastream to the bluetooth device.
Have attached the A2DP specification. Under Linux there is a project calles "bluetooth-alsa", that supports A2DP and Handsfree. Look for it at sourceforge.net.

There are several options here. It can be sent directly
on some phones, or (theoretically) through the phone,
or even redigitized from the analog (for mono).

A2DP Skipping - Solution?

This subject seems to have been beaten to death in the other device forums, but I haven't seen any direct references to this in the TyTN forums, so here goes: has anyone who experienced the ( every 10-20s) skipping problem using the A2DP profile found a solution?
I've seen a couple of registry hacks in other forums which seem to have worked for others, but nothing so far about the TyTN.
I have everything working now with WMP except this and the issue with the ring tone being delayed and coming only from the headset; see my other post this morning.
So far no other problems with the TyTN.
/POL

Skipping happens on my TyTN mostly when the WiFi radio is on. When turned off, the music skips only every now and then.

Improvement of Bluetooth Listen Music
Find this registry : :idea:
HKLM/SOFTWARE/Microsoft/Bluetooth/A2DP/Settings/UseJointStereo (Dword:1)
Change the Value to 0
Also you can add a new registry to improve the quality:
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings
Add : BitPool [Dword : 48] Maximum is 58

Yes, I've done these mods which set to stereo (why on earth have mono as default?) and select audio quality, but these don't affect the skipping.
Unless lowering the BitPool value will cure the skipping - but I want to keep it at 48 at least.
/POL

Check through my notes thread here. There's been some research going on with priority settings and specific bitpool min/max values. However, there appears to be more than just reg settings at work though. The entire device slows to a crawl too. My gut feeling is that this won't be addressed until HTC releases their first official update, rumored to be in a few weeks or so.

i have done that but still skips every 30 secs or so.

Interestingly, I could hear the same "tick" on my 8125 as well but it sounded like a slight scratch on a record. On the TyTN its magnified to this major dropout. I'm really thinking our only A2DP solution will be to wait for the updated ROM I'm afraid.
Let's hope they don't take the coward's way out and remove A2DP altogether as was done in several Operator's initial AKU2 release for the Wizard.

I think you guys should look into optimising your SD cards and trying the reg entries sleuth255 indicated. My A2DP seems to work fine with probably 99% skip free playing. I'm currently one floor above my Nokia HS-12W and am still connected to my TyTN ok in certain parts of the room. If i am right beside it or in the same room I dont get any skips at all; apart from when I lose or reaquire a GSM signal.

well, that's encouraging news efjay! Much better results than I ever got. Btw: are you running the newer DoPod rom onto your TyTN by any chance?
edit: nevermind; I just used the Wiki to crossref. If your signature is correct then you've got the standard TyTN ROM build running.

Yes im running the TyTN rom. I actually had the Dopod rom but apart from a few things in the extended rom wasnt too different so i flashed back to the TyTN one. A2DP works ok now, was listening most of the day and the TyTN battery even outlasted the Nokia battery.
Another good point in the Nokia's favour is you can re-establish a stereo connection without having to go to the BT settings - just push the Audio button and it reconnects for you and the music starts.

Some good news on my part! I've done all the mods suggested by sleuth255 - except lowering the BitPool value to 5 - I suspect that would decrease the audio quality too much - and I now have skipping only about once a minute. Much better.
How do I go about optimizing the (micro)SD card?

Check out this guide from Menneisyys
http://www.pocketpcmag.com/forum/topic.asp?TOPIC_ID=17921
Or the short version - get SK Tools (trial version should be ok, if not it costs $13) and format your card but make sure the backup FAT table is disabled.
I used it with the default cluster size values and also have other registry tweaks applied and A2DP works; I am even able to browse via GPRS when streaming music.

A2DP and WLAN - no such luck!
It became obvious to me today that using a stereo Bluetooth headset while connected via WiFi is a non starter. Continuously skipping audio and the device hangs after a few minutes and needs a restart.
There goes my dream of listening to Internet radio over a WiFi connecIttion. It works over a UMTS connection but since my carrier doesn't have an unlimited data plan, that's an expensive proposition.
Didn't HTC test such an obvious scenario?
Bummer.

@efjay:
Ok, so I'm now up to speed on SD card optimization having read through Menneisyys' post on this. Now to the nitty gritty... I have a 2gig SANDisk card so FAT16 is pretty much out due to the huge cluster size that it would create. I'm going to eliminate my FAT backup, go with FAT32/8k cluster sizes. I forget how many entries a FAT32 table can have but if that won't give me a full 2GB then I'll bump the cluster size up to 16K.
One A2DP note however: I did test with an mp3 file located in main memory and there was no improvement in skipping, so I came to the initial conclusion that SD card access speed wasn't an issue.

Let us know how it goes. I am still getting skip-free playback via A2DP. If it doesnt work maybe the additional reg tweaks I applied to the system cache are what is making the difference.

I've found another issue with the wireless stereo profile - sometimes when a call comes in, pressing the call button on the headset will answer the call, but there is no sound (caller can't hear me and I can't hear the caller). To get the call going, I have to "disconnect handsfree" from the call in progress menu and then press the headset button again.
Anyone else seen this?

joint stereo is not mono
joint stereo is merely a way to improve compression efficiency -- and can even be used with lossless (stereo) codecs

so is there any progress? I have the same trouble with my Anycom BSH-100 .. it is skipping every 30-50s

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*

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):

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...

where to buy

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):
http://forum.xda-developers.com/showthread.php?t=308752&highlight=A2DP+settings+bitpool
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:
http://forum.xda-developers.com/showthread.php?p=1677577#post1677577
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
More info about the settings:

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
