Hi Marco,
   I am most certainly not an Alsa expert. However I do use one USB to
optical spdif device. It's a an Instant Music RDX-150. Here's a link I
found:

http://www.usb-ware.com/ads-instant-music.htm

   It uses the USB Alsa driver. I thought I filed a bug report on it a
long time ago. It's a little weird how the lights on the front sort of
randomly change state but I think that doesn't effect the audio
output.

   It seems to work fine in stereo for the little bit we use it. We've
had it a couple of years. It hooks my wife's PC playing Aqualung into
our home theater receiver. I have no idea whether it will pass full
ac3, 5.1, 7.1 or anything like that. Not even really sure how I might
test that for you but we could try if it was important to you. Maybe I
can run xine and play a DVD or something, assuming my receiver
supports 5.1 on that input. I don't know.

   BTW - I have never used the inputs on this device. The ONLY thing
we do is send 2 channel stereo output from the PC to the receiver.
Nothing more.

Hope this helps,
Mark
