A2DP for WM5 coming soon...

I'm looking for a way to redirect my TomTom voice instructions from my MDA Vario through my Parrat CK3300 BT carkit sounding on my car-speakersystem by using the bluetooth stack. Now Parrot claims this isn't possible due to a phone limitation. I agree and think it's shortage of Microsoft WM5. Now I've looked up some info about Bluetooth Audio Distribution and found the following:
Advanced Audio Distribution Profile (A2DP)
AKU 2.0 for Windows Mobile 5.0 (for both, Smartphone and Pocket PC), which is expected to be released early next year (2006), will also includes support for the Bluetooth Advanced Audio Distribution Profile profile which is designed to transfer a stereo audio stream like music from the device to a headset or car radio.
A2DP is already implemented into the Samsung SGH-i300 Windows Mobile 2003 Second Edition Smartphone, however this isn't based on Microsoft's A2DP implementation but Samsung added it itself.
(Refer to http://www.theunwired.net/?itemid=2779 for more info concerning this subject.)
So if this article is based on true facts, it means that Microsoft will soon release a patch for all WM5 based devices, which enables them to receive all audio (e.g. TomTom voice instructions) through the bluetooth stack.
Somebody knows more about this subject and if it's true that after having AKU 2.0 installed, you can hear the navigation instructions through your carkit or headset?
Many thanks,
Youri Festen

there is a facility on this forum that will allow you to switch audio to and from the bluetooth, not high quality or stereo but standard quality.

There is ?
Been loking around in the threads for quite a while, but didn't find a replicatable solution...

Here you go

Tried all kind of files, but no go...
All i want is ALL audio over the Carkit (Supertooth2). That is TomTom + Phone.
I don't care if i have to trun of the carkit to return audio to the phone. But i don't want to have to reset or something.
I have a XDA (Himalaya) btw. Still with Rom 1.72 00WWE 15/03/2004 (Ext Rom 1.72.125)
Tried all these :
BA_OEM_AudioGW.CAB
BA_WM5_Voice_Dialer_2.cab
BCHS_FOR_POCKET_PC_OZONE[1].ARMV4.CAB
Broadcom Corporation BT-PPC AV.cab

voicedial2.rar

whoa it worked
i know im reaching here, but really wanted to try to stream to the new cingular 2125 (aka hct). downloaded and ran the app with my iphono steroe headphones (luv em), got intresting results.
it worked. ran the app, pushed the button on the headphones, got music. call came in, answered (with auto answer) talked, and on hangup it went back to music. however, if i ran another app on the phone such as voice tag in contacts to initiate a call, it brought in the call, but on hangup went back to the speaker. had to run the toggle on again to get headphones working, not elegant - always want more - but im a happy guy til a2dp comes out for mobile 5. thanks!

Try reading and understanding what you read before posting. See the post of dalamario that is the BTAudio on/off tool !
Is this goingt to be anter shout and wild guesses about what file or tool should "really"work ?
I tried all so called "easy" fixes, hell, i've even got a whole dump of my registry, cut through all the BT + Audio and BT + Headset threads, here and on PDAPhonehome, Howardsforum, and the reduced-to-user-bla-bla on pocketPC-club.nl.
And still zilch.....
Ow, and don't think i'm someone who wants easy answers... Think again, i've been around quite a while on PPC forums and the lot....
What i do want/like is usefull answers ans clues on how this BT and Audio stuff works, beut even after reading some on MSDN i can't find a solution yet....
That's why i jumped in on this thread, i'm not going to reinvent the wheel if some allready has the solution: Tomtom and Phone audio over BT
So i'll stop writing now, and continiu searschin for a solution... There must be one...

Sorry mr high horse, wont bother trying to help next time just in case i might not be right, but then if everyone did that no one would answer anything.

The Wizard can do system Audio over bluetooth.
This has been proved with the easy hack that allows you to activiate voice dial using a BT headset.
http://forum.xda-developers.com/viewtopic.php?t=29837
MS Voice Command leaves the Audio Gateway open after initialising, whilst Voice Dialler closes it.
So maybe try installing Voice Command and doing the hack in the above referenced thread, and then see if you can launch Voice command from your car kit. This should leve the gateway open and allow all system sounds to stream to your BT kit until you hit the button again.

Try keeping Himalaya talk in the Himalaya forum then. Posting questions about devices in the wrong forums just causes confusion.

Not Mr High Horse, but didn't you look at what you where posting ? You should know it linked to the same file, right ? If not, you really would just be 'shouting' ...
It's just that i've been reading XXX threads, and just about everyone comes up with the same, useless, files... Like nowbody really knows how it works and waht should be done to make Audio over BT possible...
We here are all trying real hard for months now, you see....

Just a little patience. Test version of Qtek 9100 ROM with A2DP already exists. It works with I-Phono bt-stereo, for example. So I think it will be released by March.

when i am on the underground the headset give a beep to tell me i have no network signal? you may not know the answer but would this over ride the bluetooth stereo signal?

Do you think that when it works with I-Phono, it will also offer us the navigation voice instructions through BT-headsets or carkits? Hope so!

Can't test it with car navigator.

if audio streaming is enabled, i would have thought you should be able to hear navigation commands.
i have used the bt audio switch that started this thread to hear tomtom commands through my headset, and it works fine.

It's nice.... I'd really like Tomtom over my carkit... Ohh, the XDA was so much easyer just soldered a Ground and Left/Right channnel into my TomTom/Leadtec connector, and plugged it in to my JVC Front-in line...
I bought the Qtec 2020 because BT seemd so much easyer

A2DP Issues

Hello.
I bought a stereo headset from Qstarz "BH-Q395S".
Using no tweaks.. Quality is low. Like low bit rate.
Using the fit4cat tweaker , sound sounds as it is higher quality BUT it is distorted in the high`s.
Is this the normal problem everyone is having ?
What can I do ?
Does ROM updates help this issue ?
Do you think the HTC headset will be better (s100)?
BTW. When paired with my PC , sound is great.

The A2DP support in pre-AKU3 MS BT stack sucks and this can't really be helped. AKU3 is said to have eliminated this problem.

I don't think so. It might be better (as are some - few! - models, for example, the Jabra), but I wouldn't hold my breath for it.

So there is hope for the future..
The question is when and if will "AKU3" be avilable for the tytn ?
Can the MS BT stack be changed?

1, the release date of the TyTN AKu3 ROM (if any) is unknown
2, the A2DP quality issues of the pre-AKU3 ROM can't be fixed (unless someone extracts the related DLL files from an AKU3 ROM in a way that is compatible with previous ROM's).
The only way to avoid the quality issues is going staright for the Jabra headsets (or going for another PDA with the Widcomm BT stack - or any Palm OS device, for that matter). See my discussions of this issue over at PPCT and HowardForums.

Or manage to hack the Widcomm stack to make it work on the TyTn like it was done for the axims.. i seriously make a donation if someone would make that happen. Heck, i'd even purchase it if Broadcom was willing to sell it..

I was really hoping to purchase an i-Mate JasJam in the next few months to use with my Plantronics 590As ... fingers crossed we have an AKU3 ROM update by then!

The HowardForums folks say the pre-AKu3 MS BT A2DP works flawlessly with the Jabra 620, unlike with the 590A and some other models.

I have a Jabra 620 and I'm not that impressed. The only headset I have had which worked completely flawlessly was an Itech S35 (but no AVRCP unfortunately).
I'm currently using a Nokia HS-12W which only hiccups if the Hermes is busy doing other things (but I've had to set the bitpool value to 48 decimal to achieve that).
All in all, I can't wait to see what happens when AKU3 arrives! Just as long as they don't break more than they fix ;-)

We all know that this BT stereo implimentation sucks! Main problem is that EDR is not implemented correctly (note bumph on this phone does not show it as others do!) BUT!! if you have tried to use ANY A2DP enhancement CABs then make sure you have usejointstereo set to 0 and pick up an iTech clip S35 (as they work OK without EDR) to use with any decent headphones and you will be fine...

The sound quality on the 620 is reasonable and it doesn't actually skip too badly, but I find that the RF performance is sadly lacking - if I use it anywhere where there's any other wireless signals around, it keeps giving periods of silence. For example, if I try to use it when shopping in the nearest supermarket to my office, from the moment I go into the store, I can only get odd bursts of music - about 1 second for every 5 seconds of silence. When I leave the store, it reverts to working reasonably again. This isn't just with my Hermes, it used to do exactly the same when using it with my Wizard as well.
The Itech S35 is the only A2DP device that has ever worked perfectly with my Hermes (with the bitpool set to decimal 58) without any skipping. Unfortunately, I really wanted AVRCP, so I've just bought a Nokia HS-12W and I'll see how that performs. So far I've had to set the bitpool down to decimal 30 to eliminate skipping, but I can live with that.

Let me disagree. EDR has little to do with this stuff as you do NOT need EDR to transfer stuff at 256 or 320 kbps. It certainly good to have but is not a requirement for A2DP. This is why, for example, BT 1.1/1.2/2.0-without-EDR-only Widcomm or Palm OS devices have no problems with the sound quality (ever tried to listen to a, say, year 2003 Tunfgsten T3 to A2DP? It is flawless.) - unlike with the MS BT stack.
I'd say this is ONLY an algorithmic problem in the A2DP encoder in the MS BT stack. (I've pretty much gone into details on the matter in my articles and over at PPCT and HowardForums. The problem can not be fixed by any recently known hacks.)

Haven't you encountered the "when there's any kind of singing, there's an awful lot of distortion" symptom with this headset?

Yes, there is some distortion but I found it bearable if I was using a decent pair of headphones plugged into the S35.

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...

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...

Big trouble with BT handset on Orbit 2. Need Help.

Well....
I happiness owner of XDA Orbit 2 (same as HTC Polaris at other form factor).
All work very fine, but one thing just kill me.
Orbit not work propertly with BT handset (Jabra JX10). I tried all posible ROMs: Bepe, BlackWidow, Rus 6.1, original HTC Polaris (WM6.0), original Germany ROM from O2. With all ROM behavior of BT handset was the same:
1. HardReset
2. Search BT device and connect it
3. Tried make call to anybody (I call to my second phone, but it doest matter)
4. First 1-2 calls all good. Sound good, mic work.
5. Tried incoming call.
6. At handset normal alarm tone, press button and..... first 2-3 sec normal sound good - then just noise (as white noise) and mic blocked.
7. All other calls like char.6. Noise after 2-3 sec.
I tried to changed all posible value. BitPool, BitRate, WaveDev and all other.... Tried stoped many service who can block BT (OBEX, ActiveSync via BT). Nothing change.
I think about hardware malfunction, but when I tried connect other BT device like external GPS reciever or HP notebook - I get normal work via BlueTooth. So, it mean hardware of bluetoth works good and with BT not work only handset.
Please, help me.

I got the same problem, but slightly different: the first 2-3 phonecalls are perfect, then there will be no sound. I tried with my 2 blue tooth headser.
with my headset, it happens 2-3 tims also.
But I met once the phone is not working when I trying normal phonecall without BT ot any headset.
I tried different ROM, it remains the same.

Similar problems with HF Jabra SP5050
Hands-free functioning with my previous cheep Nokia was excellent. Now the same Jabra SP5050 with Polaris: TRAGEDY !!!

Try turn off and on again (5 sec later) Bluetooth on Your Polaris when headset is on. Is it working?
Do it every time you start using headset. Need patch from HTC.

Yep, its work. Thanks for that. But it black magic and not good solution.
updt. It work until to first sleep (power button) longer than 5-10 min.
Then again needed reboot BT on device. F...k.

So you said you tried all kinds of ROMs. There are some ROMs out there which include the test version of the Radio ROM. I'm a strong believer of the thought, that the Bluetooth part of the test Radio is flawed and leads to results like the one you suffer.
If I were you, I'd check my Radio ROM version and if it doesnt match the shipping one (which tops out at 1.58.21.23) I'd search for that version and flash it. After the flash, a Hardreset might not be the wrong thing to do.

I wrote later that I tried flash original ROM for O2 Orbit 2. It ROM contain radio 21.23. And nothing changes.
But, I not wish change radio ROM. Last radio ROM very well and good quality of GSM and fast GPS more important for me. The more so because, BT still not work.

up.....

At me and many my friends (with Cruis) a similar problem. The first, second call - all is good. Then - break of BT communication. Works with SE is better, the Jabra is worse

Yep, tha same ****.
Today I tried Motorola H680, it good work with O2....
I think, Orbit2 or Polaris not work with BT headset with bluetooth version 1.1-1.2. Only BT v.2 and it headset just last 1-2 year ago.

Is the problem solved ?
Hi everyone !
I've got the same problem with my Jabra BT Headset. But i've found a way to make it work : in fact you have to get your headset already powered-on when you launch BT on your Cruise. Then, you can have regular calls.
Sometimes, it seems to disconnect by itself, don't know why. You have to power off everything, reconnect BT Headset, then re-launch BT service on Cruise.
Have a try and keep in touch !

It seems to me, a problem not only in version BT 1.2 or 2.0. I speak so since has bought SE 712 w/BT 2.0 and has dug into the same problems.

Have you got some news about BT & Cruise ?

Plantronics 590E with Orbit 2 works flawlessly... Distance, sound quality and voice command function is perfect without any issues..
...and A2DP, AVRCP function is same also... with mp3 or movie files... (..need registry tweaks.. i'm find these tweaks in this forum..)
Sorry for my poor English... :|

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

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
