A2DP sound quality bad

[dethl]

I'm running the BigJ 1.6u rom (I've tried many other roms too) and using a pair of Kyocera TXCKT10161 bluetooth headphones. I am listening to music and hear this high pitch whine in the background on my headphones. The only solution that I can find is to use the Widcomm BT stack but I lose my headset ability which I need.

Is there any way to make the sound quality better using the MS stack? I need my music but I can't stand the annoying extra noises the 6700 makes.

EDIT: I'll use bt-audio and tweak TCPMP - better than my headphones screaming at me.
