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;
http://forum.xda-developers.com/viewtopic.php?t=53717
You can see my (and some others) experiences with A2DP and some stuff we have tried to fix/handle it as good as possible;

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

How do you play sounds over bluetooth ?
I'm trying to understand the routes of analog and digital
sound data and how to control them.

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).

Software is not a problem. We need to understand
what the hardware is doing.
I want to buy this headset but I have some doubts about it and I thought you may help. (I have HTC Universal)
1. Does this headset really show the CONTACT'S NAME on display or just the phone number? If so, can I upgrade ROM or install patch to make it show NAME? I use Pocket Informant, if it matters...
2. Does the remote really work? With all player's software (usually use TCPMP). With my laptop on standby and closed (screen faced inside) can I simply make it start playing and foward etc??
3. Can I see the song's info on display? Like artist, song's name and all?
4. As a simple headset (on car use), is it good enough? easy of use, good sound quality on recieving and mic good quality on talking? Or is it just like "Speeker on" effect on Universal that I have to have my mouth gludded on display to talk and other person listen clearly (laptop mode)?
5. As a headset (for music and movies purpouse) is it good quality sound (better than original HTC headphones/headset that came with Universal (wired ones)?
6. I've heard there was a problem reconnecting headset stereo after a call (recieving I think). I've also heard that had o reconnect on settings... Is it true? Happens with all PPCs and all Stereo BT headsets? Or just with some brands/models? If this happens, I dont know if its worth the money, since I recieve calls a lot (would be boring to restore settings or resets...).
Can be fixed with upgrade of ROM or patch (If there is this problem with Univ).
7. Is it worth to trade a normal BT headset (jabra b250v) and stereo headset (wired that came with Uni) for this one??? It's kinda expensive... Will I be pleased or its just problems... wireless stuff??
8. how do I know if my ROM has AD2P and AVRCP. If no, how do I upgrade to it?
Please help me decide if its worth the buy!
Thanks

RE
Hi!
I'm using the SE HBH-DS970 bluetooth headset with QTEK 9000 aka Universal
1 - It shows contact names provided you've JETware Hands-free Extension installed otherwise you only have contact numbers on display
http://www.jetwaremobile.com/index.htm
2 - The remote works very well with Conduits Pocket Player v2.8's AVRCP
http://www.conduits.com/products/player/
3 - Didn't notice it can
4 - Not sure use in car (I don't drive) but it works well when use for talking
5 - Sound quality fairs vey well and its slightly strong on the bass side and not too strong on treble (comparing to BLUETAKE iPhono mini 450Rx). Did not try with Universal's wired headset
6 - This issue applies to many headsets too. Only way out is to exit the music program and re-start it and everything will be fine
7 - Why have 2 when you can have 1 integradted one?
8 - So far only the latest Universal, QTEK 9000, ROM has built-in A2DP and AVRCP.
Hope it helps
RE
Bro,
Your QTEK 9000 ROM
QTEK 9000 (Universal)
ROM Version: 1.30.77 WWE

Strange, I do not have the registry entry "Settings\". After "A2DP\", all I have is "Device1\", "Device2\" "Device3\", "Device4\".
I am using the tornado patch (not the Qtek ROM).
Anyway, I am using this Sony Ericsson headset:
- If I am playing music and a call comes in, the headset does not pick-up the music after the call. I have to shut everything down, and refresh the services of the headset.
- Usable range for stereo music is about 10-20 centimeters. So, if the Universal is on my belt, then the headset receives the music okay. Any further, and the headset does not receive the music. In other words, in my experience, the wired headset that came with the universal has longer range!!!
- The music title and contact names do not appear on the headset screen, but then I am not using JETware Hands-free Extension at the moment.
@FOSA: How is your experience, especially concerning:
- bt range (for music)?
- Resuming music after a call?
- I understand you are using the Qtek ROM (not the tornado patch)?

Sorry, missed out one other important registry entry for smooth A2DP, here:-

- 5m of open space is not an issue
- Not possible to resume music after a call, however, I just exit Conduits Pocket Player v2.8 and re-start the player again and everything (including AVRCP cotrols) work fine. NO need to soft reset and re-pairing. My AVRCP controls even work with my QTEK 9000's lid closed. All these made possible with Concuits Pocket Player v2.8
- Yes, I'm using the QTEK 9000 with latest A2DP ROM + the 4 regsitry entries mentioned above for smooth music
Thanks for the info.
I will have to try Conduits Pocket player, and maybe even upgrade my JasJar to the Qtek ROM (I am guessing that i-mate will not release any new official ROM updates for JasJar).

Hi skywriter,
The 3 registry entries are added using an improved A2DP patch available on this forum - can't remember where. However, if you know how to add these entries then there's no need for the said patch.
You can have different values after trying them out and get the minimum stutter/lag/hiss etc on your set

Where to buy
Hello!
I want to know where is the best place to buy this headset (in Europe).
Thanks
Deiota
I don't know if this place is the "best", but I bought mine from this online store in Spain with very fast service/delivery:
http://www.bluezona.com/index.php?o...18&PHPSESSID=9b2d60858e02b1e75bc53faace6b690f
They have several other models available too.
FOSA,
You seem to know your DS 970 pretty well. I have the same model and I love it I must say. I am not experiencing any hiss or reception problems except when my 9000 is in a case where the magnet is messing around with it in general.
However... I have the following issues:
- Turn BT on 9000 on
- Turn DS 970 on
Although Wireless Stereo Option in the pairing is unchecked the phone streams all sound to the headset. I have to go in and check/save and uncheck/save to disable wireless stereo.
Also I cannot get Caller ID to work correctly with the Jetware. I emailed them and sent them a log and they determined that the headset is using extra commands which is what is causing the problem. Probably will be fixed in a future release but for now, it doesn't work.
Mind you, I have tested thoroughly and did go to the trouble to backu and hard reset. Both problems persist after hard reset with only one number in contacts for test purposes.
Any ideas? (the wireless stereo bit it killing me..)
Other than that I have to say, it's extremely well behaved, stylish, handy and reliable.
Joanna
Correction: I tried the new beta of Jetware and it works fine (so far) with the CallerID checked in the Advanced Options.

I don't have this problem. Once paired my QTEK 9000 auto detects my HBH-DS970 the next time when I turned both on and 'Handsfree' and 'Wireless Stereo' options are always checked
RE
Aaaaaaa.............its not relaible
I uninstall and re-install JETware and now its not displaying name caller id
:roll:
FOSA my problem is not whether it's checked or not. I have chosen to uncheck the wireless stereo and use it only as a headset when I drive. It completely ignores the UNchecked wireless setting and still streams all sound (including incoming call ringtone) to the DS970 even though it shouldn't. Setting is unchecked and the minute I turn on the headset it acts as a wireless stereo. Have you tried this at all?
I have not tried uninstalling but 2 days later the beta still works. I have two more questions for you, well one really:
1. Does it scroll the whole name of the contact? Mine shows the number and then the name but not the whole name (which in Greece could be miles long). Just the first 10 characters. On the HBH660 I know it scrolls the name. I am not sure if this is a limitation of the headset or the software.
2. Uninstall and remove the settings from the registry. It leaves the settings behind in HKLM/Software/Jetware. Trying installing then and see what happens. I use the beta which will be released with the next week or so (or so they said).

thanks FOSA! i knew they came from somewhere... but i didn't know where. if i can just create them by hand that works too!
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!

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?

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.

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.

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...
Cheers
Damn! Streaming audio.... I'm jealous! No UMTS here yet

not to make you anymore jealous but i was streaming my xm radio off my phone... with UMTS it worked fantastic, and now with the patch there is no skipping
When I use the A2DP in wm5/6 I tray all versions BT stack~but no one could work,so I chose 2003se,IT's best for BT A2DP.
Why Helmi Do not fix that?Dose this really hard?
Yes, it's that hard to fix that. The only way we could get wm5/wm6 working flawless on BA is if we had the source code for the drivers and the testing/debug equipment.
If you know someone that works at HTC you could ask them to look for the BA devkit and sourcecodes on the storage rom... hehehe
Mine didn't skip with WM5 and did not skip when I first flashed WM6. Now it does. When I was messing around trying to connect to bluetooth devices (I couldn't connect properly), it stopped skipping for a while. I don't know if this gives any clues.

I know a way to prevented this bug,but not prefectly.
Use regedit tool,open to find software\widcom\plugin\av
add 3 dwords
Linespeed 320 (10+)
Blocks 16 or 32
Subbands 16
You will see the music quality is prefect
but the skipping frequency is above normal~
When using the asus p535,this way will surly improve the quality~and it no skipping,so I thing it must be the bug from the System~
Use win2003 have no such foolish bug.Now I set my pc back up my pda every time connected it with PC~Store the phone book in simcard~
I have no choice
Toxi,
Thanks. I couldn't add the Dword settings which you suggested because I had no Widcom file. So I loaded Helmi's 1.7 Broadcom BT driver. (Always wanted to try it. The Broadcom BT drivers alway better. Immediately after installing, my BA played music better alone and with my BT headsets. Adding the Hemi 1.7 BT cab, added the Widcom file which allowed me to add the Dword registry changes. The music sounds almost perfect.
I tested the BA with these three BT Stereo Headsets: Motorola S9 headsets; Chinese Copy Motorola BT820; and I-Phono RX450. The Motorola S9 works (It didn't at all with the MS WM6 BT Drivers). The S9 would only work if it's 12 to 18" from the BA. That's unacceptable. The BT820 chinese knockoffs skipped as usual (the skip some with every device cause they're knockoffs). The I-Phono worked perfectly with crisp clear sound and no skipping. I can also get further away from the BA but certainly not more than 3 feet without trouble.
In conclusion: Helmis Broadcom 1.7 cab worked to fix the sound problems completely with and without using the headsets. The newer headsets such as the S9 don't work all that well with the BA.
I hope this is helpful for others not satisfied with the music quality of the BA running WM6.
I wish HTC would make a Blue Angle II.
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

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
