And, with this state, can you use the built-in mic? Also, how after restoring the module option?
Yes, I can use the microphone built into the laptop. I think I can use that always, independent on whether I use the module option or not.
Also, maybe more fundamental question: how exactly "it didn't work"? Does the HDMI device appear on pipewire / PulseAudio, but the output results in silence? Or Is no HDMI listed there?
HDMI is listed in pavucontrol.
Actually it is listed there 3 times:
HDMI/Displayport 3 Output (unplugged) HDMI/Displayport 2 Output (unplugged) HDMI/Displayport 1 Output (plugged in)
But when I select it, I heards nothing from the monitor speakers. I tried all 3 HDMI/Displayport in pavucontrol because I was not sure which one was the right one, but I didn’t hear anything when trying to use any of them.
xrandr showed me the following outputs:
$ xrandr | grep connected eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 309mm x 174mm HDMI-1 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) DP-4 disconnected (normal left inverted right x axis y axis) DP-3-1 disconnected (normal left inverted right x axis y axis) DP-3-2 disconnected (normal left inverted right x axis y axis) DP-3-3 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 600mm x 340mm
DP-3-3 is my external monitor which has speakers.
After I did set that module option with modprobe and rebooted, I could select
HDMI/Displayport 1 Output (plugged in)
in pavucontrol and hear sound from the monitor speakers. So what xrandr calls DP-3-3 seems to be HDMI/Displayport 1 (plugged in) in pavucontrol.
BTW, the lack of AMD SoC stuff might be related with the device power state. A cold boot might change the situation (or trying back to an older known kernel).
I’ll try to boot again and see whether it breaks again. Currently I booted without the module option and it still works, but there was a kernel update.
