But if I didn't have the digital mixer to do my A/D conversion, the 9652 would've been wrong because it doesn't have a breakout box with analog inputs like the multiface or something else - the HDSP 9652 has 24 channels optical i/o and a stereo spdif - that's the only in and out of that card... TotalMix doesn't run under linux, it doesn't matter. Under linux, you'll be using a program called hdspmixer - it's the exact same thing (am I remembering that right? yes I think so) what is your studio/other gear situation like?
