Yes, and all those soundblasters are supposed to be 5.1 but I never
figured out how that happens, still less how to send more than 2
channels to them from pd.

AFAIK you can only get 2 channels with SPDIF, there is a 4 channel mode
but who knows if anyone uses it...
Unfortunately the board has no SPDIF input, so ADC is ruled out.
There are some varieties of Mini-ITX with IEEE1394, maybe that would be
better if there is any firewire hardware that works with linux.

Thanks for pointing this out, I'll give it a go.
