Public bug reported:
After upgrade from 20.04 to 21.04 all 3 my usb sound devices start crackling, i
have xduoo05plus, audeze mobius, audient id4.
I also tried to modify
default-fragments = 5
default-fragment-size-msec = 2
to different sugested on stackoverflow articles setting
Also this is in my config:
high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 5
I even tried to switch to pipewire, but it still the same. Possible issue in
alsa kernel drivers for usb interface, submitting bug to pulse as it default in
ubuntu.
