Hello,
I was wondering if people with USB audio interfaces have the same issue
as me. When using the microphone of my usb audio interface, the recorded
audio starts to stutter/pop, indicating buffering problems, usually when
I do something that causes a bit of load on the system (e.g. starting a
browser). A good example of this happening is here:
https://youtu.be/Vbi5f1SlXZw?si=5pjaMI4aAf6Luewx&t=380 (at the 6:20
mark, the link should take you there)
This also happens while videoconferencing with platforms like Teams and
Jitsi meet. The remote end claims I sound like a 'robot'. Reloading the
page and/or restarting sndiod (and then reloading the page because
browsers generally don't appreciate audio being pulled away from under
them) alleviates the issue temporarily.
Oh this happens on both stable (7.6) and -current. Also updated to the
latest snapshot which shows the same behaviour.
For reference:
uaudio0 at uhub2 port 1 configuration 1 interface 1 "MOTU M4" rev 2.00/1.01
addr 2
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
audio1 at uaudio1
This happens with the MOTU and the Logitech BRIO webcam (which works
fine, I use it in above video)
I've already messed with the sndiod flags, currently set at:
sndiod_flags=-s default -m play,mon -s mon -r 48000 -b 24000
Which should give a buffer of 500ms (according to the OpenBSD multimedia
page)
Throwing larger buffers at it does not seem to alleviate the issue.
Needless to say, this makes creating videos and videoconferencing
somewhat unfeasable.
Playback is absolutely fine however.
I'm kinda out of ideas. So I'm asking here. Any help is appreciated.
Kind regards,
Emiel Kollof
