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.!

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! )

Did you try the other alternatives? (I've linked them in some other threads; use the forum search engine.)

Hi,

How do you revert to the initial situation (what are the original registry settings ?)

Thanks

I am not sure, but I belive that if you uninstall it it should go "back" to normal.

otherwise, the "normal" would be

Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\A2DP\Settings]
"UseJointStereo"=dword:00000001
"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,

papex

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?
