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.
