Comment # 27 on bug 1163046 from Takashi Iwai

I don't know what is expected from my side, but the only fact is: if you don't
know about the details of your sound setup, DON'T TOUCH IT MANUALLY.  Leave the
sound setup to pipewire (or PulseAudio on older systems), and switch the audio
via the dedicated application for your desktop environment -- as a fallback,
pavucontrol.

Again, something manually tweaking is only for experts.
