I found what I can change Input Source for default sound device via mixer by this commands:
amixer -c 0 -D 'default' set "Input Source",0 Mic
amixer -c 0 -D 'default' set "Input Source",0 Line
etc
Also I have a another PCM device defined in my .asoundrc: http://pastebin.mozilla-russia.org/104988 named my_fullduplex. When I try to change Input Source for my_fullduplex by this commands
amixer -c 0 -D 'my_fullduplex' set "Input Source",0 Mic
amixer -c 0 -D 'my_fullduplex' set "Input Source",0 Line
Input Source changed also for default pcm device. I looking for a way to create custom control for my_fullduplex what allow me change Input Source for 'my_fullduplex' and for 'default' independently.
After that as I hope I can start two instance of my application and select in first 'default' as audio device and in second 'my_fullduplex' as audio device So in different instances of application I can capture voice via microphone connected to Mic jack and microphone connected to Line in jack at same time. But I dont know how to create custom control and it is possible or not. If some one know how to do it please help.
