I have a laptop with a GeForce GTX 1070 Mobile running Ubuntu 22.04. I’m able to output video, but not audio over HDMI to my TV.
The odd thing is that when the TV is off but plugged in to the HDMI port, the HDMI audio appears connected and – as far as I can tell – working as expected. As soon as I turn the TV on it disappears, and does not reappear until I physically unplug the HDMI and plug it back in (or reboot).
I am NOT able force audio to the TV using aplay or speaker-test and specifying the card/device IDs.
The solution in this thread – changing udev rules to stop the audio device from being powered off – sounded promising but didn’t do anything.
I’ve tried driver versions 545, 510, and 470 with no noticeable differences.
The problem does NOT occur with the nouveau driver.
It also does not occur when using a different laptop with Windows, or a third laptop running Linux Mint with a much older NVIDIA card (a GeForce GT 520M, if I remember correctly).
And it does not occur with an older TV of the same brand, but everything else unchanged (same laptop, OS, drivers, HDMI cable).
