I'm currently using the card in analog mode only, (have to figure out
first how the SPDIF can be used. (I remember there being some messages 
on the ALSA list).

I do have one problem though, which is hard for me to track down.
After an hourof usage  or so I get PCM errors, which don't come from buffer
underruns. Allesandro Fogar, who is evaluating the card too, didn't
have those problems. So it might be a problem with my setup.

Otherwise, S/N ratio is good for in and out.
Real full duplex. (at least 44.1, haven't tried 48, but AFAIK
48 kHz works as well)
Actually for the price of the card it's fantastic.

I don't know if the card can be used in 4 channel mode and how.

Currently the other way to go, is to hope that SBLive drivers will
be working soon.
