Audio dropout like this is usually caused by the USB audio device
disconnecting.And that is usually case by RFI. Chokes on USB cables (and all
other cables) usually solves the problem.Ensure your ethernet cables are
shielded too. Newer CAT 7 or CAT 8 cables are already shielded. And ground
your ethernet hub too (most don't have a built-in ground)I even put chokes on
all my power lines going into the breaker box to reduce what's riding on the
power.
And, if you have an outside round rod (like many I have helped) that is not
tied to the house ground either stop using it (and use the house ground) or tie
the outside rod to the house ground properly. That has also solved many RFI
problems.

This problem of occasional no audio output has been reported here by
various users, included myself. I have encountered it while running with
Windows XP and using Linux, on different hardware. I cannot remember
that an valuable diagnostic has been reported about the reasons of these
sporadic recurrences.
Best wishes,
