it's ok.  a stream can support different formats and channels.
if you find "Channels: 6" in stream0 proc file, then it means that the
pcm device 'hw:0,0' (or hw:X,0 where X is the card number) can accept
6 channels playback/capture.  if so, you can just feed 6-channels
interleaved data to the device.
well, this means also, that you have to access all 6 channels at the
same time.
