A2DP Issues - JASJAR, XDA Exec, MDA Pro ROM Development

Hi all,
Laurentius and I are looking at resolving the current issues with A2DP (Many fixes will be in our latest rom, however issues vary from headset to headset.
Some work fine, others are poor quality and some receive PDA lockups or long pauses between streams.
Please could those with A2DP issues, and the need for this protocol to work properly, post the following information.
The current Rom you are you using
The make and Model of your headset
A list of issues you are currently having with A2DP.
Please also try the following to resolve the issue.......
HKLM\Software\Microsoft\Bluetooth\A2DP\Settings\
Remove (Delete the following entries)
BitPool
MaxBitpool
and add the following
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\AudioGateway]
"Capability"=dword:0000003C
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"SampleRate"=dword:0000BB80
"UseJointStereo"=dword:00000001
Please then remove (un-pair) your headset and Soft Reset
After SR please re-pair Headset and test A2DP again.
Please keep this thread clean and only post A2DP issues with the required information listed above.
Thanks,
Cheers,
Beast

Hi Beast,
Isn't:
"UseJointStereo"=dword:00000000
to get proper stereo sounnd?

KOR!

I have latest V1 rom from Lt.Cmdr.Ivan - BT headset is Philips SHB7102 (works great with my Wizard and SEk800i). I did exacetely what U have asked for (but i have left jointstereo=0) and nothing happend. It sounds like 2s of music folowed by 15s of silence, then again 2s of music and 15s of silence. I messed with bitpool walues and couldn't find any working set. I'm afraid that's something wrong with max BT speed and not with A2DP implementation. I had BT speed switch app when I used broadcom BT stack and A2DP works great. Unfotunatelly normal mono BT headset doesnt work at all with this BT stack so I'm back to original stack

I've found that with MS stack and my Jabra BT620s the best bitpool is 33... good quality and good range (no interruptions)... jointstereo must be 1 otherwise the sound uses too bandwidth...

I also have Ivan's V1 Rom and have an Itech Radio headset. I completed the changes that you suggested and found that A2DP works well it did before the changes too. I have noticed that the sound quality may be a little better and the pauses are slightly reduced.
The main problem I have found with A2DP with all AKU0.5 ROMS is the pairing of the headset. If you soft reset you phone while the headset is on, A2DP will be auto detected when the phone comes up. If you play music then the music starts and stops and the phone becomes unstable. The work around is to turn your headset off, soft reset the phone. When the phone comes up turn the headset on and activate A2dp by pressing the button on the phone. Music then plays fine.
The registry changes you suggested did not help the above problem. AKU0.5 ROMS all seem to have this A2DP autodetect error on reset at least with my headset. Very frustrating.

Hi Maniware,
Can you please further shed light in detail on the jointstereo?
Why jointstereo to be 1 or 0?
Thanks in advance!
KOR!

It goes well with joint stereo. Seems that it needs much less bandwidth. I've heard that jointstero=1 means that there is mono sound in effect.

"UseJointStereo"=dword:00000001 << mono
"UseJointStereo"=dword:00000002 << joint stereo
"UseJointStereo"=dword:00000000 << stereo

qtek 9000 - Logitech Mobile Bluetooth Headset
I'm not quite sure if my problem is right here - because i still have the original (last build) WM5 ROM (130.96 GER, Radio 1.09.00, ExtROM 1.30.185 GER).
I encounter statics while using the Logitech bluetooth headset, which is a mono one, making phone calls impossible due to stressed phone partners ... Only the person on the other end of the line encounters interruptions, me, as calling, not.
This is the main issue for me to update the ROM, and I'm trying to find out if any of your nice new ROMs will be of help.
Anyway, I haven't tried yet I'm afraid to destroy my device ...
thanx
Anna

my feedback:
device:
itech r35
Problems:
sound muted after 2 seconds of music.
audio players used:
audio manager
windows media player
i tried your advices, but not worked for me....
Sometimes it works when i put 70 (binary) on both Maxbitpool and bitpool...but on next device activation or reboot it just stop working...

A2DP and wireless
Just to be clear, my results are when I do not have wlan activated.
I changed UseJointStereo=dword:00000000.
Quality is good and it is definitely stereo.
Still have the auto detect problem. Interesting though, if I walk out of range for a while with the headset on, when I come back into range the A2dp is autodetect and the music starts playing through the headset again, quality is good. If I soft reset with the headset on and A2DP is autodetected, the headset is unusable.
If you do any of this with wlan on the quality is very poor with starts and stops.
Also noticed that audio manager does a better job with bluetooth than gsplayer, I think audio manager may have better caching.

Freezing
I think there's a problem with the latest core os files (AKU 0.7.0)... i havent' tried the MS BT stack, but with the Widcomm, using the bluetooth for anything more than 1 min, completely freezes the phone.
It does when listening music, transferring files, etc... if BT is idle, nothing happens (except than freezing the device when the Comm Manager gets confused and enables BT instead of gsm radio).
So it seems related to the core files.
Switching on and off, transferring data thru BT is a critical task and subject to lockups.
For the record, i used to use the BT A2DP and file transfer without ANY problem whatsoever in my old and horribly-underpowered HTC Tornado (omap850 @195mhz) so IT MUST WORK!

im using your latest rom and Motorola HT820 does not have a problem with it... even in the earlier roms you cooked... even tried it in indra's xoj version and darkforce's rom..
just wanted to clear it out just so you can rule something out...

Hi,
Now that sucks,
I have the same headset HT820 and audio sucks, long pauses etc etc.
Can you post your firmware Revision for me please, it should be printed on the inside of the headband.

The same result after applying those reg mods....

Please try and install the stack found here: http://forum.xda-developers.com/showthread.php?t=291639
A2DP problems should go away, but then will come the freeze-after-1-min problems, like with my HP Stereo bluetooth headset

I've flash to your latest WM6 AKU 0.7 (WIFI Fix update 3) ROM just now. But sadly to say, the freezing thing still occurs after playing music with Audio Manager. It even freezes when watching videos using WMP. Usually around 1 minute it shall start freezing. FYI:

I had the Qtek 9000 with italian version WM5 and i flashed WM6 with no problems. if you dont wanna have any problems unzip the attached file and add in the folder the 3 files (ms_.nbf ; nk.nbf ; radio_.nbf) from your prefered WM6 ROM (I personally use the latest Laurentius & Beast ROM http://forum.xda-developers.com/showthread.php?t=325466) start into bootloader (Power+backlite+softreset) and ROMUpgradeUt.exe
VERY IMPORTANT: you have to charge your batery before any flashing

WM6 and A2DP

Hi all Gurus!
I was planning to get myself a Jabra BT8010 and plan to get it working with WM6 installed XDA MiniS.
Generally, how is the sound quality of BT A2DP as compared to normal headphones? Are there many issues in BT Stack of WM6 that might prevent nice music experience?
Also, has anyone tried BT8010 with WM6 Orwell's rom? and got it working perfectly fine?
And can we just jot all the issues/problems/solutions faced with WM6 (whether Orwells or PDAViet) and A2DP here in this thread?
Mods, the specific threads are all scattered so I thought I would start off this thread specifically for WM6 and A2DP. Please delete this thread if this topic doesnt require a separate thread.
thanks,
Sid
Works fine on mine with a Sony Ericsson DS910, and an iTech Blueband.
It has AVRCP also, so with the DS910 it supports all the controls.
Quality is probably about the same as A2DP from my K800i, but it is all quite memory intensive, so if you're low on ram it will stutter like a bastard.
i had the PDAviet 3 WM6 and the xound quality on mine was okay..its just a cheap think i bought on ebay that you plug your own headphones into. its eem sto lose some base and sound a bit tinny compaired to the same headphones plugged into my 8125 directly, but that could just be my BT receiver.
I have Nokia HS-12W and the music quality if good with same gaps in music but the quality in voice is very bad!
The voice is like talking from far!!!!
If someone solve this problem please tell us!
Im Using my Mono SE headset to listen to movies etc on the go and have noticed a bit of a drop in quality from WM5 to WM6, It seems to crackle more on WM6.
Bluetooth range is very good though, I was on a call the other day and someone came to the gate so I got up and went outside still talking on the headset only to realise my Wizard was still on my desk 10 meters away

I use iphono mini with WM6, quality in music is quite good (similar as WM5) once you add the bitpool registry key to 40 (before a lot of skips).
But used as hands-free has quite bad quality, at least in my case most of the times I have to disconnect the bluetooth and use the phone.
Perhaps the Jabra are better in this aspect.

Got My Jabra BT8010!
Hi All,
I got my Jabra BT8010 working with the WM6. I am pleasantly surprised with the voice quality. Music thru the stereo headset is also excellent, but sometimes the songs seem to slow down or plays fast randomly.
I tried overclocking, but it did not do much good.
Has anyone faced this? this doesnt happen everytime.Just randomly, the speed of song increases or decreases. Any pointers in this?
Further, Anyone knows how do I activate cyberon voice dialling thru this? The MS Voice commander doesnt work well with Indian names :-(
Thanks for the help...all. I also filled the petition for XDADEV to allow storing the ROMs at this site!

Give this cab a shot. My buddy uses it on his Mini S, says it works wonders. I don't have a a2dp headset yet. I forget what brand he has, it's a something-com I think, the one that folds up.
My BT620s is on the way, I can't wait. I will let you know how it works out.

I got it today.
The damn thing took forever to charge the first time.
I have to say I am very impressed with this thing. Works out of the box with WM6, so far no issues whatsoever. The sound quility is not audiophile level, however it is a lot clearer than I thought it would be!
I was listening to some songs that i have only heard on my crappy laptop speakers and they are awsome. I can hear a lot of things that I couldn't hear before. The bass on these is great.
the best part is that they were only like $60 US, that is less than I paid for my Jabra BT800 a year ago.
I Give the BT620s a 2 thumbs up!!!!!
btw no A2DP fixes have been applied to the Mini S, I am using PDAViet 3 so I am not sure, actually there may be some tweaks in that.
Using A2DP on pdaviet3 with the itech clip IIs headset works great for me:
PROs:
- no skipping after 20 min of mp3 playback
(EDIT: it does drop audio for one sec about 1-2 secs after initial playback, but then resumes)
- not wired headphone sound but pretty darn close
- seamless music pause/resume with incoming calls
- no problems at all with MS Voice Command
CON:
only one so far - people on other end when asked about sound of MY voice said it was a little distant/tunnel sounding (but this is more due to the mic location on the itech)
That being said, I've just "reverted" back to faria's 3.3 rom. Today screen with SPB Pocket Plus/Diary combo seems snappier.
i have wm6 and sonorix OBH-0110, and sound quality if awfull comparing to PC connection with toshiba bluetooth stack. and some cooker said that wm6 bt stack is alot worser then wm5 one.
Hi All,
I dont have this location on my WM6 Orwells: "HKLM/SOFTWARE/Microsoft/Bluetooth/AD2P/Settings/"
The "Settings" folder and the subkeys are not there. This location was there in WM5 while it isnt there in the WM6. Does anyone know where it has been relocated?
And any settings for A2DP skipping and Music playback speed uneven-ness?
Added those bitpool registry keys but they seem to have no effect. How can I improve A2DP sound quality in WM6?

Did you create those locations manually?
Even after installing that bluetooth fix cab in this thread, I still have problems with skipping and song playback speed intermittant. :-(

Yes I created those manually. Now I use Molski's AKU3.3 Crossbow style rom and sound quality improved alot. Still not on the same level as a wired headset but much better nonetheless. As soon as there is a better WM6 rom with working A2DP tweaks I will upgrade again.
An Update,
I used this A2DP fix http://forum.xda-developers.com/showthread.php?t=284974
and skipping went away. Also, music quality reduced.
I uninstalled the fix, and I have the quality back, but songs have started skipping again.
Cant MS provide for a better BT stack in WM6 with all their development prowess??
Would going back to some stable ROM like Molski's or Farias WM5 help?
Faria's WM6 and A2DP
Another update....sighhh
I updated my Wizard to Faria's latest fully loaded WM6. The skipping reduced a bit, but thats about it. The Music speed is still intermittant.
Seems like I wouldnt be able to enjoy this gift. Why cant things just RUN....
I am guessing, changing ROMs wouldnt help...or would it? Does Widcomm stack work on WM6? Anyone with this experience?
The next ROMs I am gonna try are:
1. WM6 MBE
2. Farias 3.3 AKU
3. Molski's WM5
After that i will try selling my Jabra BT8010.

Anyone figure out a cause behind the intermittent skipping and speed fluctuations when playing music over bluetooth? I'm using the XDA Mobile 6 release 2a ROM with my BlueAnt X5i headphones. Everything works for the most part. But about 10 to 15 minutes it will drop audio for a few seconds, then start back up again. Annoying but I can live with it.
What's really irritating is the fluctuations in playback speed. For some reason playback tends to speed up every 5 minutes or so. When I skip ahead or go to the next song and it's fine. Then the issue recurs again in 5 minutes... repeat cycle.
I've tried using different mp3's of different bit rates and that doesn't seem to have an impact. I've also tried different players - WMP, TCPMP, GSplayer, Mortplayer, etc. All seem to behave the same way when it comes to variations in speed during playback. Any ideas on this one????

A2DP help on ppc-6700

Hello,
I am having some issues getting A2DP working on my sprint ppc-6700, I recently got a moto s805 stereo bluetooth headset and cannot figure this out. Searching didn't help much since the recent AKU upgrades confuse (at least for me) what should and should not be done, so please bear with me.
The headset work with windows (and linux) via A2DP and with my phone as hands free, I can make calls.
I just upgraded to kirvin's 3.5 clean & simple ROM, I thought this would give me A2DP "out of the box".
When I start any player morts (3.31b59), coreplayer or wmp I get a blip of audio and then for most part nothing. Sometimes after it stops, I get audio out of the speaker or wired headphones, however setting the s805 to "wireless stereo" seems to keep the audio stream over the headset, but I only get a low hiss or random blips of sound. The AVRCP seems to work as I can control mort's skip fwd & back even when no audio is coming out of the headset.
It seemed like the poor thing couldn't keep up so I also tried XCPUscalar to overclock the processor, but that did not help either.
Are there any reg hacks to get his working?
Is the widcomm stack an option and should I consider it?
Should I be using a specific file format/bit rate? I tried just about everything including mp3 128bps with no change in performance.
Should I be using another AKU version or build?
Are there any decent how to's? I wouldn't mind learning a bit, but just getting it done would be fine too.
Thanks in advance.
-shiggs
I figured this out, but still don't have a sure fire way of getting it workikng every time.
In short it will only work if the wireless stereo icon pops up when I enable bluetooth, if not I get a blip of audio and them nothing or just nothing at all.

Bluetooth headset with WM6

hi,
i resently bought a heaset sagem BT sh1, (BT stereo headphone) and tryed to use them on my universal originaly with the 02 uk latest vanila rom, but it didn't reconised the headphone as such only headset, so i search on the forum and find that it was because of the missing A2Dp stuuf, so i upgraded and flashed the rom to WM6 wich resolved some of the problem but not totaly,
The headset work not problem to Lisen phone call and stuff, i can even lisen to the sound of the universal ok, screen tap and so one,
but when i start media player to lisen music, it does work for 4 second and then it stop, it doesn't shutter, it just stop, and work again for 4 second only if i close mediaplayer, and it work again for 4 second, i try the reg hack but didn't change anything, i try the a2dp upgrade as well no success,
i try other player no success, what get me is the fact that i cannot lisen any sound that are longer than a few second,
can anyone help me,
thanks a lot
ps i did pass almost all day looking for a solution on my own, without result.
my rom of my universal is Jwrightmcps Crossbow ROM Update 2.02.00 WWE

Hi!
Using "Resco Registry" or another registry editor program, find the following key:
HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BtA2dpSnd
add new DWORD:
Priority256 with value 250 (decimal)
This should solve any lag problems. But to get hi-quality sound, you also need to tweak parameters here:
HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings
These are the values that result in the best possible sound:
UseJointStereo = 0
BitPool = 58
MaxSupportedBitPool = 60
MinSupportedBitPool = 30
Good luck
WBR, Draco.
hey thanks for the tips but it didn't work, the probleme isn't that i have lag, but that i simply have no sound that is longer than a few second. exept on headset phone mode, and the quality is very good anyway, after i did that reg hack it was even worse, (no offance intended) no i can't have any sound longer than one sec, and in the registery under HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2 DP\Settings
i didn't have any settings, not one. can it be sommthing missing in my wM6 rom ?
Hi,
I have a similar problem using Helmi WM6 rom...I have been using itech bluetooth headset for almost a year now without problems, after switching to WM6, each time my phone rings, i have to press once to connect the bluetooth to the phone and another time to answer,,,It was fine with the WM5 roms..any ideas?

WM6 A2DP settings

Hi,
I am using O2 xda mini s, and i just bought a sony ericson HBH-DS970 stereo bluetooth earphones.
I am using WM6 Xplorer Rom and radio version 02.25.11.
Currently I am a bit frustrated with my bluetooth earphone as the quality is very poor eventhough I read that the quality of the sound if used with other bluetooth handphone / pocket PC is superb.
I have ben searching this forum to either tweaks the registry or any patch to improve the sound but currently I'm still lost. I found one old post (WM5) which guide us to tweaks -> HKLM/software/microsoft/bluetooth/a2dp/settings....
but my problem is that there is no settings folder under my a2dp, there are 4 folder with label 1,2,3,4.
Are there any way i can improve the sound quality???
will changing the radio rom affect the quality of bluetooth reception??
Please enlighten me..
Thanks

Try the settings from cduncan...
If there is no registry entry, you will have to manually put them.
You can change the bitpool setting for quality of music.
HTH
Cheers Sids,
I have already do as you said... previously went to that post but feel lost, and since the thread have over 100 pages, therefore i feel inappropriate to ask you or duncan.
One more thing though, can i ask you what is your personal preference on those settings?? I cant put a lot of bass, because it will sound terrible, like broken speaker.. what todo??
cheers mate
p/s My problem is that the quality of the sound that coming out of my BT earphone is just poor (although others are highly recommending this DS970). I have no problem with pairing it with my wizard or the playback.
I have play around with the BitPool and the only difference that I notice was the volume level, not the sound quality. any advice??
One more thing, is the selection of Radio Rom have any effect to the quality of the bluetooth signal i.e. to the output in my BT earphone??? Help...
Thanks again
Hi,
I cant say about your BT headsets. But I confirmed these things - Updated firmware from the manufacturer (Jabra for me) and the quality with other A2DP enabled (maybe nokia/SE) phone.
I have set my bitpool setting to 60 which is Farias default, but he placed the reg entry in AD2P folder instead of A2DP by mistake.
I am using equalizer settings with TCPMP for the nice sound, which I dont get with Windows Media Player. Maybe you could try that out.
Even after those settings and tweakings, I dont think BT headsets can replace wired headsets for an audiophile. You will only just get passable sound quality. Maybe its got to do with bandwidth that BT provides.
Lastly, I may be wrong, but Radio roms are only used for GSM radio. Its got nothing to do with BT.
Gurus, please correct me if I am wrong anywhere.

I'm using faria ROM Real Thing and using Oakley OROKR as my bluetooth stereo. But I have unusual problem. When I listen MP3 from pocket music 4.3.4 my OROKR produced a lag sound. Sometimes the sound was disapeared and suddenly back to normal again (with lag of course). I have try my OROKR with my PALM Treo 650 using A2DP s/w it's produced same quality like my MDA. Is this happen cause the registry setting or my OROKR problem? Help me?
PS: If I used OROKR to call it's 100% normal
For what it's worth, i have tested my plantronics pulsar 590a (bt ver2) with other htc devices with bluetooth ver 2 and audio was excellent. the wizard only has bt ver 1.2 and that is maybe where sound quality is lost. just a thought...
did you buy the headphones on ebay? Got mine on ebay and I was very disappointed with the sound quality. i checked online and, for my surprised, i discovered that what I got from ebay was a cheap fake. I bought a new set from sony shop and voila, they work perfect. Sound is amazing..with the SE k800i i am using from time to time. Couldnt get them to worjk with my xda2i tho

Stereo bluetooth (A2DP) issue on Polaris

I just bought a bluetooth headset from Sony : DR-BT21G.
The pairing works just fine, I can listen to music or make a phone call. I can even watch a divx on TCMP with the sound in the head set and no problem.
The only thing is that as soon as I put the Polaris in my pocket (jacket our trousers) the sound stops, then comes back, then stops again, etc. The pairing is not broken, but the sound keeps coming and stopping.
This is even worse when I'm walking.
If I take the phone on my hand, the sound does not stop anymore.
I have changed the following registry keys as I read on other posts but it changed nothing:
HKLM/Software/Microsoft/Bluetooth/A2DP/Settings/BitPool - change to 48
HKLM/Software/Microsoft/Bluetooth/A2DP/Settings/MaxSupportedBitPool - change to 58
Any idea were this could come from ? Any other good or bad experience with this combination ? Is it just bad luck and I have to change my headset ?
Thanks for your help.

Quick update
I have installed the two patches for bluetooth, released by HTC official web site.
But this did not fix anything...
Yo dude,
I've got the same problem with a Sony Ericsson HBH-DS980.
I've not tryed to install the patches because i just received my cruise from repairing service.
I'll try and tell u.
Bye
i too have this annoying problem with no joy from the hotfix.... ring htc tell them you want it fixing under waranty i am!
1. Did you either restart your phone or restart the blueooth after making the registry changes?
2. If you did and it still didn't work for you, I would reduce both bitrate settings to the 28 and then restart either the blueooth or the phone which should fix your issue pretty much immediately. I would then up the A2PD settings at increments of 4 until you figure out the Sony DR-BT21G bitrate threshold. (Again be sure to restart either the phone or the bluetooth after each increase.)
FYI: The hotfixes aren't supposed to fix A2DP issues.
Thank you very much Sonus for your help.
Unfortunately I tried to tweak the bitrate according to your advice but it does not change anything.
I put the bitrate down to 2. It is true that I have less cut, but still, the connection drops from time to time for somes seconds.
Is the idea of this bitrate to catch the one of the device or is it : the lower, the better connection ?
I did not noticed any effect on the quality of the sound though.
Notice that I restarted the Polaris each time I change the value.
If you have any other idea or comment this will be more than welcome.
Here's the solutions guys.

After implementing everything in there, I soft resetted the device, reverted the AKU back to .0.4.5(HKLM\System\Versions\AKU) then installed the HTC BT Fix and voila! No more issues. Excellent! Calls notifications are now coming direct to the headset.
By the way, i'm also using Sony Ericsson HBH-DS980

Yep i reverted aku to .0.4.5, installed the HTC BT fixes, and now i have no more "holes" in sounds.
But what is this solution ? i don't really understant what is it for?
I have the same headset as you, did u see any difference in the quality with the solution you mensioned?
Thx for ur future answer
David
More tweaking... unsuccessful
I have done all what was written in the thread :
- deleted the two regkey (MaxSupportedBitPool and BitPool)
- set the AKU value back to .0.4.5 (the initial value was .1.0.0)
- reset the TC (many times )
But still, I suffer from cuts in the connection where the sounds just stops in the headset.
I just want to precise that I never suffered from low quality of the music. All the time I can experience very high quality sounds. Only the headset stops playing for half a second, two seconds, then play again, then stops...
Any help more than welcome....
i have same problem but with my non-stereo, non-A2DP headset. when i put the phone in my pocket, sound become "choppy".. anyone know a solution for me?
