Description

Jan Lübbe writes about his experience with using BT headsets for gsm calls:
I setup a call using FSO/zhone, which switches to gsmhandset.state. Then
i loaded GSMBLUETOOTH, and setup the headset using bluez.
Now the transmit path worked fine, but i couldn't hear anything in the
headset.

The problem here seems to he the "Capture Left Mixer" control is set to "Analogue Mix Left". When i now switch this to something different ("Analogue Mix Right") and back, the receive path starts working. Paul and Jörg suggested it might have something to do with DAPM. Also i noticed that changeing "Capture Right Mix" changes "Capture Left Mix" in paralell, but doesn't fix the audio path im my case.

Workaround:
amixer sset "Capture Left Mixer" "Analogue Mix Right"
amixer sset "Capture Left Mixer" "Analogue Mix Left"
