missing from pulseaudio(both as input and output), but I can see other
HDMI or USB sound devices I may have attached and I can switch to them
and they work as expected.
Interestingly the device works when playing a WAV file usi

still exists?

I still lost sound after setting "realtime-scheduling = no" in
