[alsa-devel] Setting Input Source

Hi,

I wanted to set my input sources and control volume through the mixer api from a 'C' code. I am required to do this without using alsa utils. Please guide me as to how I can set my input source to say 'Mic' and also adjust say Front Right channel volume.

It would also be nice if there was a mini tutorial on the alsa page which explains how to do this basic stuff.

Thanks and Regards, Chandrashekhar
