Description Dax Kelson 2013-01-28 03:32:03 UTC 
Description of problem:

On a fully updated Fedora 18 install on my ThinkPad W520 laptop, sound isn't working through HDMI/Displayport. 

My laptop is in a ThinkPad docking station, and I have a Dell U3011 LCD monitor connected via Displayport on the dock.

kernel-3.7.4-204.fc18.x86_64
xorg-x11-drv-nouveau-1.0.6-1.fc18.x86_64

In looking at ftp://download.nvidia.com/XFree86/gpu-hdmi-audio-document/gpu-hdmi-audio.html I see statement "For HDMI audio to work, both monitor_present and eld_valid must be 1."

Does that statement from the nvidia document apply to nouveau?

# cat /proc/asound/card1/eld#0.0 
monitor_present		0
eld_valid		0
# cat /proc/asound/card1/eld#1.0 
monitor_present		0
eld_valid		0
# cat /proc/asound/card1/eld#2.0 
monitor_present		0
eld_valid		0
# cat /proc/asound/card1/eld#3.0 
monitor_present		0
eld_valid		0

Those are all the eld devices I have.

It's currently not expected that DP audio will work, whereas HDMI should.  Closing this bug as it's an upstream issue, and will make it into Fedora once it's supported.
Comment 3 Aleksandar Kostadinov 2013-11-06 06:47:31 UTC 
There seem to be people that now have DP audio working albeit not exactly as needed:
