ION HDMI Audio Issue with newer drivers (eg. ubuntu 13.10) - Kernel 3.12.6 + 319.76

Dear NV Dev Team,

since monthes, I face the strange problem what without any special reason, I am not possible to get any audio over my HDMI link in my ZOTAC ION-ITX P mainboard which features a NVIDIA ION graphics. The 100% identical setting with older drivers (see below) works absolutely fine.

I am testing using an OpenElec build which comes with the drivers listed in the title - Kernel 3.12.6 + 319.76

output of: aplay -L -> http://sprunge.us/GFLP
output of: dmesg -> http://sprunge.us/hICe
output of: cat /proc/asound/card0/codec* -> http://sprunge.us/Bcdd
output of: amixer controls -> http://sprunge.us/CRZR

speaker-test -c2 -r48000 -Dhdmi:CARD=NVidia,DEV=0

no sound at all -I can report that sound is defnitly dead here while it works fine with a GF430 in a different system. Its only ION related.

If there is any way to support you on this special driver issue (works well in very older drivers) I can support you 24/h by providing an ssh access to my testing HTPC rig.

Im not the only one faceing this problem and its NOT openelec related. It seems to be a very special HDMI issue on ION builds together with newer nvidia drivers.

See this developer thread:

If there is any way to help, please let me know. Thanks and best regards

Kraut

Edit:

Same logs with a working older version

output of: dmesg -> http://sprunge.us/YNSH
output of: cat /proc/asound/card0/codec* -> http://sprunge.us/bPCA

speaker-test -c2 -r48000 -Dhdmi:CARD=NVidia,DEV=0

works well

Krautmaster,

It is very similar to the following problem:

No hope…
