Bug Description
AMD64 3000+ on K8N4-E Delux motherboard
On Ubuntu-5.04 works perfectly (NFORCE-CK804 sound - snd-intel8x0)
On KUbuntu-

after kernel-2.6.14 - NO SOUND!!!
I suppose this problem is linked whith ALSA, becouse ALSA-1.0.2/4 - sound works perfect!! After 1.0.4 - NO SOUND!!

I have read that only OSS supported
Copied - below - comments from an nvidia forum
So for a recap on the Nforce ALSA + SPDIF optical + Ubuntu issue this thread is about, these are my (personal) results to date. As stated before, the Nvidia drivers are OSS only, not ALSA. Hopefully this will help anybody maximize performance with their hardware + Ubuntu configuration wishing to use ALSA and help avoid some troubleshooting time! Anybody else with feedback, please feel free to add to the list.
Ubuntu 5.04, Stock Audio drivers, 2.6.10-k7 kernel:
-OSS: Works
-ALSA Detection: Works
-ALSA Analog (0,0): Works
-ALSA SPDIF (0,2): No output
Ubuntu 5.04, NVIDIA Nforce 1.0-0306 drivers, 2.6.10-k7 kernel:
-OSS: Works
-ALSA Detection: Works
-ALSA Analog (0,0): Works
-ALSA SPDIF (0,2): Works (perfectly)
Ubuntu 5.10, Stock Audio drivers, 2.6.12-k7 kernel:
-OSS: Works
-ALSA Detection: Works
-ALSA Analog (0,0): Works
-ALSA SPDIF (0,2): Kinda works (requires toggling of IEC958 in alsamixer, very often)
Ubuntu 5.10, NVIDIA Nforce 1.0-0306 drivers, 2.6.12-k7 kernel:
-OSS: Works
-ALSA Detection: Does not work
-ALSA Analog (0,0): Does not work
-ALSA SPDIF (0,2): Does not work
Ubuntu 5.10, NVIDIA Nforce 1.0-0310 drivers, 2.6.12-k7 kernel:
-OSS: Works
-ALSA Detection: Does not work
-ALSA Analog (0,0): Does not work
-ALSA SPDIF (0,2): Does not work
Here is my /dev/sndstat output (Ubuntu 5.10, stock audio drivers, 2.6.12-k7 kernel)
Sound Driver: 3.8.1a- 980706 (ALSA v1.0.9 emulation code)

apologies to contributor... I orig. copied notes to check my sys out, not sure where from.
Have Dapper 6.06 on with Xgl added and evrything from scanner to printer working well. Have been considering nForce- Linux-x86- 1.0-301 pkg on my AMD 2600+ on A7N8X-E.
cheers
