Hi Peter, Thanks for getting back to me. I'll do all of those things next week, when I have access to my laptop again.
I only noticed the problem after I upgraded from 6.3 to 6.4, though it is possible that it was present before and I didn't notice, so I'll check.
I have tried it on two other TGL laptop and HDMI audio works fine on them, so I cannot reproduce the issue on the three laptops I have tried on my side.
This might be product specific issue?
Can you test also 6.4.1 on it before going to 6.3.x? https://archive.archlinux.org/packages/l/linux/linux-6.4.1.arch1-1-x86_64.pk... https://archive.archlinux.org/packages/l/linux/linux-6.4.1.arch1-1-x86_64.pk...
There is even 6.4.0 available: https://archive.archlinux.org/packages/l/linux/linux-6.4.arch1-1-x86_64.pkg.... https://archive.archlinux.org/packages/l/linux/linux-6.4.arch1-1-x86_64.pkg....
I'm using pipewire on the machines, but to be sure, can you test plain ALSA as well?
to see the PCM devices: # aplay -l | grep HDMI card 0: sofsoundwire [sof-soundwire], device 5: HDMI 1 (*) [] card 0: sofsoundwire [sof-soundwire], device 6: HDMI 2 (*) [] card 0: sofsoundwire [sof-soundwire], device 7: HDMI 3 (*) []
on this laptop the HDMI PCM is card 0, device 5: # speaker-test -c2 -Dplughw:0,5 -W /usr/share/sounds/alsa/ -t wav
non sdw machines will have the HDMI PCMs on 3-5, so likely: # speaker-test -c2 -Dplughw:0,3 -W /usr/share/sounds/alsa/ -t wav
aplay/speaker-test is from alsa-utils (pacman -S alsa-utils)
