Now that's quick! As far as I can see (I once had 5+ years of experience in
HP-UX, but that's 10 years ago, so please excuse me for unclarities) the
same behaviour as reported in
lspci reports the card/soundchip allright
dmesg report nm256 as being blacklisted, loading stopped?
Still I can modprobe snd-nm256 (by hand or automatic during booth) but that
doesn't change a thing.
alsamixer complains about default: no such device (mixer in Xfce also only
lists a default device with no controls):
alsamixer: function snd_ctl_open failed for default: No such device
When firing up TOTEM, I get a warning about ' sound device busy' and no
sound (video playing all right).
When I lsmod | grep snd I get an awful lot of sound modules loaded including
the opl3, opl3sa2, cs4231 which don't seem to be needed (hw not listed in
lspci) and might be 'hijacking' some hardware portions.
Trying to modprobe ad1848 io=0x530 irq=5 dma=1 dma2=0 which is suggested in
one thread as workaround is not possible due error on param io (although
settings are exactly the same on my system as reported by BIOS):

That's about it I think. I checked most of the forums on this issue, found
at least 5 other people reporting same, but no thread ended into a solution.
I checked whatever I could on the alsa project, but this proved of no help,
looks this is more about real sound cards, not simple onboard chips.
Thanks again for getting in touch!
