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.
Thanks for all the work you've done on this!
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.pkg.tar.zst https://archive.archlinux.org/packages/l/linux/linux-6.4.1.arch1-1- x86_64.pkg.tar.zst.sig
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)
I still haven't got my laptop back yet, but hopefully I'll be getting it back today. If so, I'll be able to look at this over the weekend and get back to you.
Best, Alex
