Interesting. I did the same thing to test the input and output of sound cards-- distortion, noise level, etc. I have also used to to test loudspeakers. The microphones definitely do not have -90dB noise floor unless you are recording stuff at 120-130dB SPL. Anyway, I agree that alsa should not be producing overruns. > > For debugging at this stage I just have > > LineOut -> LineIn > . > > The overrun happens even when I do _not_ feed anything into LineOut, i.e. from > ALSA point of view I _only_ have capture process and no playback process. > > But we are not discussing my rig. > > Thanks, > Sergei. > > > ------------------------------------------------------------------------------ > Xperia(TM) PLAY > It's a major breakthrough.
