This is up-to-date f32 amd64.
From time to time I find that I do not have sound, and then
pavucontrol shows no configuration is available. Sound is via HDMI to
the monitor (TV). The internal sound device is not used.
So far the only way out I found is to log out/in, but this is not
ideal. Is there a way to make the system (I suspect it is X) see the
sound device and enable it? Maybe with a udev command?

/sys/devices/virtual/sound/seq
/sys/devices/virtual/sound/timer
When I have no sound I am missing the last two devices.
In case it is related, there is also a KVM instance running on this
machine.
Does it fix it if you run
pulseaudio --start
That should re-initialize pulseaudio, picking up available devices. If
the problem is some kind of race condition between X and pulseaudio as
it seems to be because it is intermittent, this should remedy it.
I am rather sure I tried this to no avail. Next time this happens I will keep
a detailed record of all the actions I take and the results.
I don't think this is directly caused by X, as X should not be creating
virtual sound devices. But, I'm no expert.
I suspect X, me not being an expert, because this is sound over HDMI which X manages.
