#25 Can't change volume from mic on headset

[The_Gremlin]

Hi i try different headset with this project.
Logitech Mobile Freedom and conceptronic Earbridge
they response perfectly on volume setting on the
speaker, but they don't response when i change the mic.
volume in the mixer (kmix, of alsamixer). When i mute
the mic, i can still record my sound. I recently (1
month ago) download it from cvs ver. 0.4c. I also thied
whith Canyon CN-BTH1 but this one has very bad mic (to
soft sounds), i must almost eat the mic to record any
sound !

Is it possible the boost the mic in alsa ? I hope
anyone can help me!

I have wondered the same thing.

In the case of KMix, the mixer named "BT Headset" has two
output controls, labelled Master and Mic, and a single
switch, labelled Loopback.

The Master control affects the volume of the headset's
speaker, but the functions of the other two controls I
haven't discovered.

Looking at the code, the two mystery controls seem to both
have to do with "loopback". But...the trail goes cold there.
