I think someone on one of the lists (ardour-dev, maybe) managed to do
this. There was a lot of messing around, however,
and much as I like M-Audio cards I wouldn't recommend this approach to
someone who just need a lot of analog I/O.
OTOH, doesn't the Hammerfall DSP have a multi-channel analog interface
as one of its options?
