[NUC11PAHi7, Realtek ALC256, Mic, Internal] Behringer 1202USB mixer's default usb audio driver clicks

[Stephen Hazel]

maybe pulseaudio, maybe alsa, i don't know.

I have a stock kubuntu 21.10 (except for 2 files where i used a "too old" fix that didn't work)

Any audio going to my Behringer 1202USB mixer has clicks about 2 per second.
That mixer is crackly on startup and shutdown but is new.
Could be something to do with powersaving?

This is a fresh install of kubuntu on my ibm nuc11i7.
I've tried Fedora kde and no repeated clicking.
Windows doesn't click.
But Fedora kde is junk - can't even connect to github :(

Other devices going thru the mixer don't click. Just the usb audio.
Other audio devices on kubuntu like hdmi or bluetooth audio work fine.

This is maddening :) click click click click...

others have the issue too. See...
