You also have to configure the routing of all the signals that can end up at the input of the ADC. See the comment at the beginning of xonar_pcm179x.c. > 2) How do I control volume of sound while recording? The aux and mic inputs go through the analog mixer section of the AC'97 codec, but the line input bypasses that and has no control. (The DAC and ADC of the AC'97 codec are not used.) Regards, Clemens
