I set IGain to some reasonably high value and mic volume to zero as this just feeds input to output: $ aumix -q vol 100, 100, P pcm 71, 71 speaker 0, 0 line 0, 0, P mic 0, 0, R cd 0, 0, P igain 80, 80 line1 0, 0, P dig1 100, 100 phin 0, 0, P phout 0, 0, P video 0, 0, P kmix reports that "Capture" is on. This is aumix's igain entry. The magic is in alsamixer. The trick is to turn OFF "Mic As Center/LFE" | Card: SiS SI7012 ? Chip: Realtek ALC650E ?
