Hi, I have some problems with 6 channel sis 7012 device - I'm using it as 3 stereo channels. I trigger 3 different instances of aplay at once and I get underrun messages from aplay. What does this mean ? How to solve this (bigger buffer? ) ? It sounds like it is interleaved in short chunks (all channels are heard on all channels) - so it's not really bearable. Regards, Robert.
