Hi,

Audio over DP and HDMI work fine on Windows 11 with my DELL G15 Ryzen 7 5800H NVIDIA RTX 3060 notebook and monitor with speakers.

However, on Linux it doesn’t display the neither HDMI nor DP output options when attached to the same monitor mentioned above.

OS - Ubuntu 22.04
Kernel - 5.15.0-39
Driver - 510.73.05
Setup - Laptop with an external Monitor over DP connected (also tried HDMI)

I’ve tried solution proposed on thread “No option for audio over DisplayPort / HDMI” by user xKGx, but it didn’t work.

The audio output of the monitor is actually detected fine by the driver:

Doesn’t it show up at all in gnome contorlcenter - audio?

Hi!
Did you solved this issue?
I have the exact same hardware and OS as you and I have the same issue, that is, the HDMI audio option doesn’t show in gnomecontrolcenter audio

EDIT:
The only audio device that shows in gnomecontrolcenter is the AMD one (Family 17h…)
lspci output:

Apparently it seems that the NVIDIA audio device is missing from some Ubuntu internals…

The AMD device is the only option available in the sound output device.

No. The only option displayed for selection in gnome control center - audio is “Speaker - Family 17h (Models 10h-1fh) HD Audio Controller”.

I have the same problem on RHEL. Can this be resolved please?

After I

  1. installed the old nvidia-driver-470 driver
  2. pulseaudio -k && sudo alsa force-reload

everything worked. I don’t know if point 2 is needed

Had the same issue, can confirm that erezn64’s steps worked for me. Rig was fairly similar to OP, and also I did not need to use step 2. After reverting the nvidia driver and rebooting, my HDMI audio from my monitor was displayed again.
