[linux-audio-user] Audio interface recommendations

Sorry if this gets asked every five minutes. I'm looking for a decent quality linux-supported interface for a laptop. Low latency is important. Should I aim for USB or Firewire? (Or PCMCIA? Do they even make those?) 24-bit is important. 48 kHz at least, but I guess 44.1 is acceptable. More than stereo in and out is kind of nice, but not required. Compatibility is important. :-) Alternatively, point me to information elsewhere. The problem is that anything I can find online is from 2+ years ago. Alternatively, please help fill in this list, especially ones you have personal experience with, so people don't have to ask: http://alsa.opensrc.org/index.php?page=Alsa+Preferred+Soundcards Jon
