In theory it should be easy - the CMI8370 chip on the M-Audio card is used on motherboards and many other sound cards, but getting the digital inputs to actually work is another matter. The DiO 2448 doesn't have oodles of connections, in fact it's rather spartan and has no analogue in at all, just SPDIF I/O (both optical and coax) and analog out for monitoring. I have a cheap MD deck permanently connected to it and if I really want to record analog audio I use that as an A/D converter! -- Anahata anahata@xxxxxxxxxxxxxx -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827
