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.pkg.tar.zst https://archive.archlinux.org/packages/l/linux/linux-6.4.1.arch1-1- x86_64.pkg.tar.zst.sig
There is even 6.4.0 available: https://archive.archlinux.org/packages/l/linux/linux-6.4.arch1-1- x86_64.pkg.tar.zst https://archive.archlinux.org/packages/l/linux/linux-6.4.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)
So I had a similar issue with the same machine a couple of days ago. I was in a Zoom call and the other person's voice started sounding tinny and robotic. I was using the 6.4.8 kernel at the time, but this time I wasn't using HDMI audio, just the laptop's speakers. In this case, I just rebooted into the 6.1 kernel and carried on my call and unfortunately didn't have a chance to grab my dmesg log or anything.
In general the laptop's audio has been fine with the 6.4.x series kernels (I've watched hours of TV with the laptop's speakers, for example), except for the problems I was having with HDMI audio and now with this one Zoom call. I haven't had any problems with previous kernels and I've had the laptop for just over a year.
Any ideas? I tried running speaker-test with the laptop speakers and, not surprisingly, it worked fine. I'm away and don't have a way to test HDMI audio at present.
Best, Alex
