The same problem occurs with Portaudio on this device (or similar) - it would 
be great to just be able to open one device with 4 channels, or 2 stereo 
pairs.

I had wondered whether it could be done by some card-specific definitions in 
eg /usr/share/alsa/cards as is done particularly with PCI cards??  Anybody 
any ideas?

Gabriel, could you post the multi pcm you worked out for this, as it may help 
others?
