Made some quick record (guitar from emulated output of an amp,
microphone vocal) nothing to say, work perfectly. Nice preamp - for me
- clean, no hiss, no background noise, nice dynamic, can hear all my
  bad notes and bad fingers on the guitar :) 
The line input - jack - work also perfectly, respect the color of my
preamp (Warm Audio)

Did not try the optical I/O as i do not have any devices for it.

Thanks UC2, thanks MOTU.

Anyone have access to the Alsa project card's list and update ?
