AFAICT, snd_intel8x0 is indeed the correct driver for this card. If you
google for this lspci output you find a MEPIS page where they claim that
the card works without problems with this driver.

That looks good, too: One audio device, one midi device, a timer, two
mixers. (Disclaimer: I have no experience with midi devices, but I don't
see why a midi device should interfere with your sound output.)

OK, so some process might be blocking the sound devices; most probably a
sound daemon. (Are you running Gnome or KDE?) Post the output of this:
lsof -w | egrep 'snd|dsp'
