I am having the same problem when using USB audio device:
uaudio0 at uhub10 port 7 configuration 1 interface 0 "Burr-Brown from TI USB
Audio DAC" rev 1.10/1.00 addr 3
uaudio0: audio rev 1.00, 2 mixer controls
audio1 at uaudio0
There is a short interruption in sound when browsing. I think, the
exact time this happens is when Firefox launches new content process
on opening a new tab. There's 4 such processes by default, and it
looks like the issue mostly goes away when there's more then 4 tabs
already open.
Issue can be reproduced without involvement of sndiod or a media
player by just running cat > /dev/audio1 < /dev/random. I was unable
to pinpoint any reliable triggers, other than Firefox. Nothing happens
in Chrome. Playback on built-in audio device is not affected.
Let me know if there is any other information I can provide.
