This thread is in response to numerous posts/requests for a fix to a bluetooth A2DP soundquality problem.
As pointed out in other posts, the libraries for Bluetooth (liba2dp.so etc.) have a setting for ‘bitpool’ which is fixed to a low value by default.
People – including myself – are experiencing 2 major issues with Bluetooth audio over A2DP protocol with default bitpool values (or so we claim) :
1) The highs tend to sound 'fuzzy' and sometimes crystalize.
2) Higher bitrate mp3s will break up as if there is a buffer problem.
As someone who produces music and owns a media company, I have a keen ear and equipment that allows me to confirm this problem at least on my end.
It should be noted that this has been brought up in various threads Eg:
http://forum.xda-developers.com/showpost.php?p=16021615&postcount=664
http://forum.xda-developers.com/showthread.php?t=1082220&page=2&highlight=a2dp
The purpose of this thread is to establish a genuine problem and implement a fix.
We would welcome input or any user experiences relating to the above issues.
Are we also able to determine if A2DP is piping the audio over SBC or passing MPEG audio direct to the headunit to decode which should result in much better quality.
It would be helpful if we could find some documentation on the format of the /etc/bluetooth/audio.conf file as various settings in there can help/hinder connections and audio quality a bit.
I'm all for improving the bluetooth support/quality given that I rely on it in the car for hands-free, music and navigation.
@JF-GINO You would probably have access to an oscilloscope if you're running a media company, any chance of running the output from a bluetooth connected device through that with a few sine waves to see if it is compressing/clipping the audio?
Thanks guys. I will try and send the two lib files today.
For the purposes of testing, I ask you do not try and compare the files, as obviously that could influence results...
I'll post the files in a zip and anyone interested can try
- their stock bluetooth
- file A
- file B
And make any comments they wish on quality, both absolute and relative...

As soon as we get the modded files, I can post the isolated diferences between waveforms from each as a comparison.

Yep, Unfortunately I don't have the files available until monday. If I posted links, then it would negate benefits of blind test unfortunately.
I am subscribed to this thread anyway. Remind me on Monday to get the files

Hi Pulser, knock knock
I'll be more than happy to help with this, since I bought a Bluetooth headset without searching around about any problems, and here I am, facing horrible sound quality...
Samsung Charge here
and I have the same problem. I feel like taking my phone and drive my car over it. I would do anything for a library that works on this stupid droid phone.

Yes my Master...pleassse
OK... As before, I ask that you do not try to work out the paths to these files or anything. Just try them out Then post feedback. And no hex editors, or comparing checksums... That's no fun.
File A: http://www.villainrom.co.uk/SGS2/VRTweaks/a2dp/A.so
File B: http://www.villainrom.co.uk/SGS2/VRTweaks/a2dp/B.so
Rename to liba2dp.so and put in /system/lib/ and reboot etc. Then comments welcomed
I've done all you said, but I'm not able to tell the differences about file A and file B, in my opinion the sound quality is the same as default liba2dp.so
Droid Charge.
I get less hesitation with A than I get with B and I think both are doing better than my current stock. I will keep testing A more.
Ok very interesting.
Tomorrow if everyone is done, I'll tell you what each file was...
Please wait until the evening I would like to test it to but unfortunately I can't download it on Android I have to go via my computer. Android shows me just a ****ed up version of the code.

Okay here's my challenge to you...
I came across this link over at XDA:
http://www.pocketpcthoughts.com/forums/viewtopic.php?p=391825.
So I did a little Google'n to see where this phone was available...and of course it's not available to us telecommunication-ally challenged US folks.
So here's the company that sells them; but of course they're in Dubai:
http://www.iteqonline.com/en_index.asp
After some more research I found the new updated ROM for this phone, and so I proceeded to unpack it so I could find the applications I wanted.
So--my challenge to you is who can provide for us the following applications from this ROM?
1. Answering Machine (Figure 7)
2. Background Effects (Figure 11)
3. Phone Recording (Figure 12) - granted I don't think this will work on the phone I want to try it on
4. Java Applet (Figure 27)
5. Voice Recorder (Figure 30)
6. Filter SIM and Send DTMF (Figure 20)
7. Magnifier (Figure 24 and 25)
All items should be in their own respective cab files for easy install for anyone who wishes to use it.
Thanks and Good Luck!
You can download the dumped rom from here
You'll need 7-Zip to unzip the archive. 7-Zip is available at http://www.7-zip.org/

On the Answering Machine....
First the Wizard has a hardware limitation that prevents call recording unless you are using speakerphone. I would assume this would eliminate the Answering Machine ability.
Second, my assumption would be that it would be in the PhoneDialer App. So you would need to install their Phone.dll and the control panel applet for the settings.
Third, a registry dump would be useful to see any hooks to the AnswerMachine.dll.

Any thoughts on where to get the registry dumps?
I'll do some more Google'n
I would love to see someone rip out the answering machine. I think a lot of people woudl find this very useful...
I just took the java app (exe) out of the dump and dropped it in my storage card on my mda. it seems to start up fine. i dont have any jar files handy to try out. It shows an option to install them from either the storage card or "my documents". Im no tech wiz but it seems like someone who knows what they are doing could get all of these features, or maybe some of them from this to work on a wizard.

Due to the hardware design of the Wizard, WM5 has no access to the incoming audio stream. bluetooth routing is also done independent of the OS as I understand it. There simply is no way to 1) send audio out to the GSM Phone conntection or 2) record to other person.
The idea of an answering machine on your Wizard is a pipedream.
Previous post deleted.
Nice challenge, I'm interested in the answering machine.
I would be interested in the Cyberon Voice Commander which appears to add a lot of features to the relatively inferior voice speed dial we have. Also the Easy-Touch Menu would be nice, it adds the option of phone profiles and a few other handy items on one menu. It looks like it's a non resident program also so it would be handy for our performance challenged phones.
I don't have any experience with ROMS, otherwise I would attempt this myself. Is this possible?

Wow I am glad I didn't know this when I downloaded and installed PMRecorder. Although the calls are quiet (unless using speakerphone) they can still be heard. But I assure you they work. If we could get the answering machine to turn on the speakerphone automatically, we could even screen calls!
Maybe the answering machine is a new upgrade to Voice commander!
Hi!
I've been reading a lot of these forums about activating A2DP with a mono-bluetooth headsets, and found (in different places) some different ways, (change a couple of registry settings and with some pocket pc/headset one had to change a file called BTAGExt.dll)
I have made a CAB file for these hacks and also included the file "BTAGExt_new.dll" I call it _new because I change the registry to locate this new file instead of the old, that way one doesn't have to overwrite the dll file and can, if problems occur, change in the registry instead. The file is needed for some (me included) that are having trouble with music playing in the headset for about 10seconds.
Anyway, i have made a self-installing cab file for this, so that other people may use it easily, without need of hacking the registry, one does not need to use btaudioon and similar program to make this work,
EDIT: AS many people pointed out, here are the instructions to USE this , sorry for that:

It is nice to see my little hack being used
BE AWARE:
*VoiceCommand DOESN'T WORK!! (since my cab disables it in favour of all-sound in headset)
*I take NO RESPONSIBILITY if this crashes your phone or anything else, USE IT AT OWN RISK!
* It only changes this things:
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"UseJointStereo"=dword:00000000
"BitPool"=dword:0000003a
"MaxSupportedBitPool"=dword:00000050
"MinSupportedBitPool"=dword:0000000e
[HKEY_LOCAL_MACHINE\Drivers\Builtin\BtA2dpSnd]
"Priority256"=dword:0000003c
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"LaunchApEnable"=dWord:1
"VoiceCmdDuration"=dWord:15180
And copies this file: BTAGExt_new.dll to \Windows (or whatever windows dir you have)
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\AudioGateway]
"BTAGExtModule"=string:"BTAGExt_new.dll"
Then do a soft-reset and voila, the sound should work.!
This worked great with my X01HT and Motorola HS850.
I used this too with my Sony HBH-60 bluetooth mono headset and it worked perfectly for me too .
Much better for listening to podcasts while in bed!
(no more strangling myself with earphone wires! )

I am not sure, but I belive that if you uninstall it it should go "back" to normal.
otherwise, the "normal" would be
Code:

"BitPool"=dword:0000003a (this setting just changes the soundquality)
"MaxSupportedBitPool"=dword:00000050 (this too delete if not wanted)
"MinSupportedBitPool"=dword:0000000e (and this, delete if not wanted)
[HKEY_LOCAL_MACHINE\Drivers\Builtin\BtA2dpSnd]
"Priority256"=dword:0000003c (delete if not wanted, better quality)
[HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand]
"LaunchApEnable"=dWord:1 (KEEP!)
"VoiceCmdDuration"=dWord:15180 (change to 30seconds or whatever, dword:30)
And copies this file: BTAGExt_new.dll to \Windows (or whatever windows dir you have) (delete this file!)
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\AudioGateway]
"BTAGExtModule"=string:"BTAGExt_new.dll" (change to BTAGExt.dll)

Thank you very much.
I use the audio to bluetooth feature with skype as it would otherwise send the sound to the loudspeaker, which, in a public place is not really convenient.
Now, with the code to "on" the sound and the code to"off" it, maybe there would be a simple way to create an app which would toggle from one state to the other? would you know how to do that ? alternatively, is there some kind of scripting tool for the ppc that I could use ?
thanks in advance,

Interestingly, this makes A2DP to transfer everytig in mono on my other MS BT stack-based devices, as has also been pointed out in my related article - are you sure this is the original value?

I believe that it is, at least on my device, but I may be wrong, it was long since I did my cab file. so not 100% sure no,
I was as curios as you, could it be that it uses mono to save bandwith? and thereby increase the range of the bluetooth?
but hey, I am no expert, I roughly took reghacks from around this forum and put together a cab file, I tried to make the cab to produce the best sound availible to a monoheadset, and nothing more, nothing less.
as it were a couple of weeks ago I since I did this i don't really remember every detail of it, but I believe most of this is stated in the hermes_wiki

Mic on bluetooth headset
I wanna know if I installed this file to use something like Skype, can I not only hear the sound from my Bluetooth headset but also speak through the headset too?
How do I get back to normal?
Hoping someone could help me out. I tried installing the file above. The installation process went well, but immediately following the soft reset, I noticed that my phone screens and response to menu picks was considerably slower. My phone locks up all of the time, and I am unable to toggle the bluetooth on and off. I tried to uninstall the application, but I get a message at the end saying that it was unable to completely remove the program. Wondering if anyone could help me to get to the registry and change the settings back to normal. HELP!!!!

Thank you for the cab/hacks. None of the other alternatives worked on my 8525. Now if someone could incorporate this into someway to switch between modes, that would be great. Right now, I install and uninstall the cab several times a day! I get nervous that the registry will get corrupt from all of the install/uninstalls.
Thank you very much!
Hi!
thanks for all the appreciation about my cab! I am happy to see that others are using it and are happy about it
I also noticed that some people has problems with it,
dhenry88: Try and install it again, otherwise, try and revert the setting yourself, I posted the "original" settings a some time ago in this thread, so go get a reg-editor and hack it
because that is all the cab-file does, changes registry (and copies a file to /windows/system32
however, this file is not important for the os itself (because I change the registry to find the changed file, not changing the file and overwriting the original.
but sorry to hear that it had such bad performance on your phone, it shouldn't do anything like that, but hey, every phone is different.

Indeed this is a great little program and I'm very thankful for it. Like lantern, I think it would be great if someone could figure out a way to switch modes easily as I'm unable to initiate a voice call through my Bluetooth headset with this program installed. I too have to install/uninstall the cab many times each day. I’m certainly not complaining, just expressing a wish.

Check this article out... it has information on the methods used to hack bluetooth enabled devices.
The easiest way to avoid this is 1) Turn your BT off if/when you're not using it 2) Set your device to "Not Discoverable by other devices." 3) Smash your friends PDA to bits...J/K
Even so, those clever hackers always seem to find a way around an obstacle, if they didn't we wouldn't have the useful wealth of information found on this website... Not all of em are bad.

Ok I am not an expert on this but while various bluetooth attacks may allow access to phone records an such (particularly on older phones) non of them should allow complete browsing of the file system an a brand new WM5 device. Your device is a TyTN equivalent correct?
I think what has happened is that at some point your friend had a chance to pare the two devices so now he has complete access. Check your bluetooth settings and delete any devices listed there. Also delete any incoming ports and uncheck 'make device discoverable'. This should solve your problem. (If not I would very much like to hear about the technique used - out of sheer scientific curiosity of course)
And by the way, if he does this to you more that once to prove that he can, he is not much of a friend...

HKEY_Local_Machine\Software\Microsoft\Bluetooth\A2DP
I my experience trying different roms on both the trinity and the wizard, deleting the whole A2DP folder has produced the best results. I assume that the headset also is a big performance difference for everyone. I think that once you delete that folder, the settings automatically self regulate to the best/optimum.

Hi m8, are u sure you mean the WHOLE of the A2DP folder? Surely it's just the "Settings" sub-folder, as the parent seems to contain device specific data for the headset(s) you have paired?
Even so, I totally agree with the principal... delete all from the "Settings" sub-folder and the A2DP is DEFINITELY giving the optimal quality stereo! (Remember to let the two devices skip etc. a tiny bit when u first kick off a song/media file as they have to be allowed to auto-negotiate the optimal connectivity settings between PDA and Headset... but once that is done, it's pure joy all the way!!)
Cheers, Moz.

Yep. It is the whole A2DP folder. After I pair a headset afterwards, if I look into the registry again, the A2DP folder has been created, with only the settings folder in that. Which confirms that the ppc and headset can create their own optimal settings.
ie
HKEY_Local_Machine\Software\Microsoft\Bluetooth\A2DP\Settings

I'm curious, what was your prroblem before? did it skip/pause often? I record all my music with the lowest possible bitrate, so quality is not so much an issue to me. maybe the sound is poor because that is the best your hardware can properly support(?)
either way, can you not you not use the tweak prog to use mono?
Alright
I have deleted the settings folder the high tone looks to be les but I am stil working on it.
I can stil not understand it what went wrong ,I had the Imate jam with The A2dp patch from HTC it was perfect ,you would think that they make it better the next time but it's les .

it had a high pitch in it, high bitrate and stereo at the same time gives sound problems.
so, or a lower bitrate, or no stereo was for me the solution.
meanwhile, i switched to INDIGO WM6. haven't tried BT stereo headset.
but thats another subject. see trinity mobile 6 sub-forum...

Hi m8, are u sure you mean the WHOLE of the A2DP folder? Surely it's just the "Settings" sub-folder, as the parent seems to contain device specific data for the headset(s) you have paired?
Even so, I totally agree with the principal... delete all from the "Settings" sub-folder and the A2DP is DEFINITELY giving the optimal quality stereo! (Remember to let the two devices skip etc. a tiny bit when u first kick off a song/media file as they have to be allowed to auto-negotiate the optimal connectivity settings between PDA and Headset... but once that is done, it's pure joy all the way!!)
Cheers, Moz.

heyz i cant find this registry! i'm a noob here. how exactly do i find this registry to delete? lets say from my pda, i go file explorer, then wat?
i'm having the sound loss problem by the way
you need a registry editor on your pda, use google to find one, i used the shareware version of SKtools, if you use the find option it works fine.(shareware was only up to show six lines in registry)
hope it helps.
okay, erm, searching for bluetooth doesnt show me HKLM (local machine). The closest is HKCU\Software\Microsoft\Bluetooth. and no A2dp folder

if it's not there, then you have the same as if you had deleted it already.

i just purchased sk tools. yea, now i can find that directory lol. i've just deleted the entire a2DP folder, and will try out my headset again later. hopefully it solves my sound loss problem, i will post my results here later. thanks to bbobecky and stormyb for your patience. hope this works
alright, now its worse. once the sound stops, it DOESNT COME BACK ON!!!!!
bump for unsolved problem
Ok... did the usual search thing... haven't read or found any new information on this issue.
Considering it (BT FILE FUNCTION) to be one BIG omission on the Android platform and/or with the HTC handsets, I am interested to know if the functionality of file transfer (and whatnot) has been made available, will be made available or has been put into any of the ROMS... to ANYONE's knowledge?
Thanks in advance for your replies.
let me add on, does anyone know if SPP or HID profiles were added also?
I know damages Rom does send/recieve, stereo audio, and the basic Bluetooth stuff.
Darch legend does the same plus Bluetooth ftp.

Sorry double post.
**BUMP**
Wow... I find it hard to think with all the Dev's here nobody has ANY insight or anything to say about the BT issue? I know the profiles have been updated for the 2.1 release, but that's about it. No word of FILE functions? Wow...
Well, in any event, I appreciate ANY word on this subject.
TIA
Yes, it appears so:

Not sure if this is widely known or not, but BT file transfer works out of the box now. I paired it with my Mac and sent a file with no add-on software. I couldn't make that work in 1.5.

Note, That is a push from the computer to the phone. I installed BT File Transfer from Market to try phone to computer...no dice. It errors out. At any rate, it's an easy way to send a wallpaper or update.zip.

Sorry for the delayed response, but that File Transfer is Bi-Directional? If so , that's awesome... Just looking for more information, thanks.
