Hi guys, I'm going to buy one of these cards, and I was wondering what about the differences from one to each other and concernig ALSA's support. By ALSA's website seems they are completly supported, but I would like to have some users' confimations. On RME website I focused this words: HDSP 9652 is the long-awaited successor of the well-known PCI card Project Hammerfall (DIGI9652). Like the original Hammerfall, HDSP 9652 offers 3 x ADAT optical I/O, ADAT-Sync In, SPDIF I/O and word clock I/O. On top, there are 2 MIDI I/Os and TotalMix, a DSP-based real-time mixer/router. apart from MIDI I/Os which I do not care about, I didn't understand what TotalMix will do on HDSP9652 and under Linux. Thanks in advance to anyone who will help! Michele
