I can't tell from the ALSA page whether or not the Echo IndigoIO is supported or not. It appears to be supported on the big list on the ALSA site, but the driver page is empty. I've tried using my Google-Fu to no avail. I've also emailed one guy who appeared to be working on a driver based on a listserv post in November, but he never replied. I'm curious if any of you know anything about this. I'd really like to know one way or another, since the only reason I haven't made my laptop a Linux machine is the issue with the Echo Indigo support via ALSA.
