If you are looking for pro-audio interfaces that will work with Linux your choices are limited to certain cards from RME, M-Audio, and AudioScience. Common desktop sound & MIDI needs are well-served by the Audigy and SBLive! soundcards from Creative Labs. USB audio and MIDI interfaces known to work under Linux include devices from M-Audio, Edirol/Roland, and Tascam. Linux-compatible PCMCIA digital audio interfaces are available from CoreSound (also for some PDAs) and Digigram. If you need a serial port MIDI interface the MIDIator enjoys Linux support. Please consult the ALSA Supported Soundcards page for current information regarding drivers for specific devices. Readers are also well-advised to search the archives of the Linux Audio Users mail-list for reports and evaluations from the field.
