I'm going to acknowledge this issue just to let you know someone has seen it, however, there isn't really anyone to assign this issue to right now. Hopefully in the not too distant future this will change.

I know this problem too. The audio is sometimes distorted.

Maybe it will work to use another class on the bluetooth stick (hciconfig hci0 class 0x400404) and (modprobe -r ehci_hcd). This will work better (but not optimal)

Just curious if people who were having this issue are still having this issue with the latest chan_mobile? There has been quite a bit of work on it by mnicholson over the last few months.
