Hi,
I'm using a Mitsumi WML-C29AH bluetooth serial adapter.
Every bt function works well but when I try to send/recieve audio data
using bluetooth-alsa package I've got noisy audio during playback and
very noisy audio during recording operations. 
I'm using a 2.6.22 kernel on arm pxa cpu with alsa-utils 1.0.15 and
bluez-libs and bluez-utils-alsa 3.22.
The adapter is binded to bluez stack using "hciattach /dev/ttyS1 csr 921600".

To setup the system I paired the bt headset, created an .asoundrc file inside 
my home directory and execute bluetoothd-service-audio.
Then I try to record/playback audio using aplay/arecord utils but noise issue 
arise. At this point if I perform a hciconfig on the system the TX counter for
SCO packets always reports 0.

I'm also using same setup with a USB BT adapter and everything works well.
Any idea? 

Thanx in advance
