Actually I'm able to use the card with mplayer (I discovered this just
now, previous tests failed or I was probably just clumsy):
mplayer -ao alsa:noblock:device=plughw=0.0
The sound is distorted though, probably 44.1 vs 48 khz thing. But that's
due to the unfihished driver IIRC. Nevertheless, my previous assumption
that no programs were able to use the alsa driver was wrong. Sorry.

ALSA ERROR hw_params: set (FORMAT)
value = S16_LE : Invalid argument
This is the error probably, I'm attaching complete std.err (std.out was
empty) from:
pulseaudio -vvvv 1> std.out 2> std.err
Also bear in mind that the internal nvidia sound card is installed too
and shows itself in the log.

Well the driver worked out of the box with Fedora 8 and 9. Something
changed in F10. I know the driver is not finished, but it worked fine
for me. Even recording from the analog input.
Any chance you'll look at the emu usb drivers again and finish them?
Thanks again for having them at all.
I'll show this thread thread to Lennart Peottering from pulseaudio.
Hopefully he can weigh in.
