odd.... Try running "sudo ossdetect -d -v" and "sudo ossdevlinks -v -r". Also, post the output of 'lspci -vnn' for the device..

Odd. The pci id should be recognized by OSS... And oss_hdaudio is there too.. Can you pastebin /var/log/soundon.log somewhere?

I've made a compiled tarball of a patched OSS at http://www.mediafire.com/?itcqkj5njtg. Get it and extract the tarball into / as root (or with sudo) (e.g. "sudo tar -C / xvf oss-patched.tar.bz2" etc.). Then cd to /usr/lib/oss/build and run "sudo sh install.sh". Then shutdown old OSS if its there ("sudo soundoff") and start patched OSS with "sudo soundon". Does it work?

installed it with "cd / && sudo tar xvf /home/nuckin/oss-patched.tar.bz2" and ran the install script, no errors were presented

soundoff unloaded stating no mixers presented, soundon resulted in a kernel panic :(

correction, Kernel Panic about a second after 'sudo soundoff' including on shutdown/reboot

Sorry, I did test this, but couldn't test the nvidia path. Lets try another idea: http://www.mediafire.com/?ynyihtyt4md instead.

No luck, still kernel panics too on unloading

More specifically on the kernel panics, it only happens when issuing "sudo soundon" after a "sudo soundoff"

No panic at boot or shutdown. But still no sound

thanks again for the prompt replies and the help :)

OK. If you compare the ossinfo output with the one in the soundon.log file, you'll see it's different.. Try this: http://www.mediafire.com/?dw3ttzmywzz

Still no dice, "sudo soundon" takes much longer to execute now, but beyond that same panic and no sound
