[linux-audio-user] What does underrun mean with aplay ?

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.
