AD2P with stereo BT headset problem

[voipster]

I have a stereo AD2P BT headset, the Abe BT 55F (no built-in mic - speakers only) that pairs sucsessfully, but I get no audio. All audio still comes out phone's speakerphone.

Abe BT 55F Specs here:
http://www.abe-hk.com/english/products/8044/8044.htm

The specs say it supports AD2P stereo, but can't seem to get an audio to play on the headset after successfully pairing it with my XV6700 running a PPCGeeks WM6.1 ROM. I cooked in acbToggleBT 0.8 (Description: Toggles the audio gateway) thinking that might enable the audio. But I'm thinking this might be for mono BT headsets.

I thought AD2P headsets worked pretty seamlessly on WM6.1?

I then tried BTAwm6.cab, another BT audio gateway program, but that didn't work either. I did previously get my now lost "mono" Jawbone to work using BTAwm6.cab, but that was several cooked ROMs ago, so who knows if it would work now.

Anyway, any suggestions?

Maybe I'm just not understanding how to toggle between the phone's speakerphone and the BT headset? I know for some mono headsets, you had to first activate a Voice Command by pressing the headset button. Not sure if that applies to stereo headsets with no microphone - thus no Voice Command capability.

Ok, I got the audio to work "somewhat". I had to go into Settings, Bluetooth, right-click on the BT device, and choose "Set as Wireless Stereo".

Now the problem is the audio is very choppy. I know I read a fix somewhere for that. Anyone? Plays for 1s, then random 5-10s of silence, then plays 1-1.5s

use a free app called btaudio.

I know about btaudio. Didn't seem to work for my stereo BT headset. The default Microsoft BT stack on my WM6.1 ROM resulted in very choppy audio. Mostly silence. If I paused the music, waited, then clicked play, I'd get 1/2s - 1s of audio. Sometimes none.

The solution after much trial & error (including trying several registry suggestions) was to install Helmi's Universal Broadcomm Stack (Test).

Unfortunately, this stack is 7MB when installed and I don't think it uninstalls the Microsoft BT stack, which no doubt also takes ~7MB of memory.

Didn't try installing to my Storage Card, but I assume it would fail. I don't see this popular stack in any of the "pre-canned" ROMs. It would be great if I could simply use BuildOS and check a box for this BT stack and uncheck the Microsoft one. Thus, I wouldn't be using 7MB x 2 (14MB) of RAM - only 7MB. Again, just a guesstimation.

Anyone know how I would go about cooking Helmi's Universal Broadcomm Stack and not the Microsoft one using the BuildOS tool? Or do I have to cook my own custom ROM (and read up on how to do that)?
