First thing to try, as suggested elsewhere, try removing your tuner card temporarily. If audio comes up, then we have found the conflict. If not, try "acpi=off". Lastly, you can try downloading a daily snapshot from ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver/ and building it with "./configure --with-cards=hda-intel --with-debug=detect". Once you build and install it, type "lsmod|fgrep snd|awk '{print $1}'|xargs rmmod" to remove all sound modules, type "dmesg -c" to clear the dmesg log, then "modprobe snd_hda_intel" to load the new modules. If you still don't get audio, type dmesg to see the latest output and email that info here.

Hi Peter. Sorry none of my suggestions produced any positive results.
As regards your mobo with only one PCI slot. That has to be quite pathetic.
You used to be able to get mobo's with 5 PCI slots, and I've been hunting for
a new atx mobo, to put in a case that I've had for some time. I have found an
atx one with 3 PCI slots, and a couple pf PCI express ones, and am waiting
for it to arrive (Asus M2N-X Plus). Not too expensive 52.50 euros. It too may
have a dodgy onboard soundcard. It will be interesting to see if the sound
works when it arrives.
Yes, do post to the alsa-development list. I hope someone there can help you
to get the sounds back up and running.
Nigel.
Nigel,
The mobo was was my own stupid fault - I bought it in a hurry and didn't research properly! It does have two PCIe slots but there's precious little in PCIe that Linux seems to support at all yet.
I will probably go the mobo replacement path eventually (then my 15yo son can have this one - he's been bugging me for one for ages!)
I am going to try one more thing and that is to install a fresh Ubuntu desktop onto an external drive and just check that the sound comes up there...
