Comment # 3 on bug 1206760 from Takashi Iwai

I see that you've installed both PulseAudio and pipewire on the system, and
they might conflict with each other.

In general, pipewire is preferred over PulseAudio for the newer system, as it
has a full compatibility with PA.

Please try to install pipewire-pulseaudio package.
  % zypper in pipewire-pulseaudio

This will replace pulseaudio and co with the own subsystem.  After the package
installation, reboot, and retest.

If it still doesn't work, please upload the alsa-info.sh output again.
