--- Comment #3 from Tanu Kaskinen <tanuk at iki.fi> ---
There was an error from the kernel driver that caused the card to be unloaded
from pulseaudio:

What happens here? After unloading the card, 11 seconds pass and the card
becomes available again. Did you unplug the card and then plug it back in?
Based on your problem description, and the fact that this happens several
times, I guess you didn't touch the sound card, it just periodically disappears
and then comes back.

34 seconds pass, and then the card is removed:

[log excerpt removed, because I don't think it is very informative after all]

5 seconds later the card is back:

[log removed]

21 seconds later the card goes away again:

[log removed]

...and 5 seconds later the card is back again:

[log removed]
