That's the problem: no thread is using audio... But:

Here was the clue: I have Realtek and /dev/audio0 

/dev/audio0 is correct. But Firefox is really using /dev/audio (that has
to point to the real device) and /dev/audio was pointing to /dev/audio2
(perhaps because I was also testing NetBSD 10 beta from time to time for
infelicities with the framebuffer default font and size, and the
numbering changes).

Doing:

# audiocfg default 0

solved the issue.

Thanks again!

Best,
