Actually, you don't need to try this; I had a sudden doubt yesterday, but
in the end it is fine and there is no problem.

Fwiw, I've seen this happen too, on a laptop, with hdaudio0.

If you reboot the machine, the device seems to be keeping its previous
"state", and is not reset. It looks like NetBSD doesn't reset it manually
either.

If you shut down your machine, wait a few seconds, and then boot it again
cleanly, the problem never occurs.
