[linux-audio-user] Delta 66/new mobo question

Greetings: eBay lists a number of these cards for sale, some with pretty good prices. However, I do have a couple questions before laying out the dinero: Is the Omni breakout box just as usable under Linux as the regular 4x4 box ? Is the S/PDIF fully supported under ALSA ? Is the MIDI I/O fully supported by ALSA ? I realize that the ALSA site answers these questions, but I want input from users. I'm also in the market for a new mobo, but I can't break the bank on it. I'm currently using an 800 MHz Duron CPU: what would be a suggested upgrade for a Delta 66-based studio, especially WRT the CPU ? Any and all suggestions will be vastly appreciated ! Best, dp
