No Audio Over HDMI with NVIDIA GeForce GTX 1650 Mobile / Max-Q on ElemantaryOS 6.1

Graphics / Linux Linux
1

My laptop is connected to an external monitor via HDMI. Using nvidia-driver-515, the monitor’s speakers do not appear in the drop-down menu in my audio settings. This is most notable because nvidia-driver-515 is the recommended driver. Here is my
nvidia-bug-report.log.gz (285.4 KB)
and my current Kernel is 5.13.0-51-generic
any help would be appreciated, thanks!

looks like the audio subfunction gets removed. Please post the output of
grep 10de /usr/lib/udev/rules.d/* /lib/udev/rules.d/*

Please delete

/lib/udev/rules.d/50-pm-nvidia.rules
/usr/lib/udev/rules.d/50-pm-nvidia.rules

then run
sudo update-initramfs -u
and reboot.

Woow! problem solved! thank you very much!
what kind of magic was that?
in a very short way, what was happening?

It was an old, now unneeded workaround to get runtime pm for nvidia working. It was simply removing the audio device from the pci bus. Don’t know why this was still installed on your system.

Nice one! I was struggling with this for over a week.
thank you for your help!
