Hi all,

Does someone have experience with microfone gain in sipXtapi? 
I’ve made a sipXtapi compilation for Linux and made a connection between two 
PC’s.
I used the sample programs PlaceCall and ReceiveCall. My microphone input has 
two
channels, left and right. When I’m using the right channel the communication is
acceptable, but by using the left channel the communication is too quiet. It 
seams,
that sipXtapi amplify the right channel more than the left channel. So I 
searched in
the source code and the only proper file I found for microphone gain was
“MpCodec.cpp”, but I couldn’t find that left and right inputs are intensified 
differently. 
By making voice recording outside of sipXtapi (using the Alsa program “arecord”)
there was no different between left and right channel.
What could be the reason, why the two Mic channels are amplified differently?
Perhaps there is something I didn't consider so far.
Thank you very much for your help!

Regards
Karsten
