Mine (not cheapo USB interface):
uaudio0 at uhub0 port 20 configuration 1 interface 1 "MOTU M4" rev
2.00/1.01
addr 7
uaudio0: class v2, high-speed, sync, channels: 4 play, 4 rec, 0 ctls
audio0 at uaudio0
uaudio1 at uhub8 port 1 configuration 1 interface 4 "Logitech Logitech
BRIO"
rev 3.10/3.17 addr 7
uaudio1: class v1, high-speed, sync, channels: 0 play, 2 rec, 2 ctls
doas /usr/bin/sndiod -s default -m play,mon -s mon -ddd
Does that also happen with sndiod defaults?
Those are the defaults (save for also grabbing a monitor mix and
running with -ddd in the foreground to get debugging info)
during livestreaming:
Can you please test with plain aucat first?
I did.
Quote:
The aucat sounds good in the beginning, but sometimes the sound is
high
pitched and artifacted
and then I gave the example of the youtube link that has the same
symptoms
to give an audible example (because it sounds exactly like that). Bare
aucat
does this too. It's intermittent and it recovers, and later it happens
again.
rsnd/0: play hw xrun, pused = 3360 / 3840
Does that mean your machine has no other audio device,
given that this on is rsnd/0 ?
It has, it has uaudio1, that's the microphone in my webcam.
Since my good condenser mic is on rsnd/0, I don't use the
crappy webcam one of course.
The aucat sounds good in the beginning, but sometimes the sound is
high
pitched and artifacted which is what Alex was referring to, as can be
heard in one of my livestreams:

To be clear: if it's a live stream, does that mean
you are recording the 'mon' subdevice with aucat?
How exactly?
mon is for grabbing a monitor mix from the sound card, e.g. for
capturing
audio that comes from a browser or anything else (game, whatever) that
produces sound with your soundcard. Makes sense to grab that when
livestreaming.
