Audio crackling after update in USB sound card

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1720 / 2 Years ago, thu, november 3, 2022, 3:32:48

With two USB sound cards (presonus audiobox and behringer xenyx q802) I have crackling sound after the kernel was updated to 5.13.0-37.
Tried on three different machines with Ubuntu 20.04 and 21.10.
Audio output from onboard audio is ok.
Output from USB sound card has irregular peaks (faster than every second).

I found this:

Upgrading to 5.13.0-37-generic breaks audio with external audio card

which is very interesting, but doesn't tell what to do to get it working again.
I have no older kernels I could revert to. Any suggestions?

I mean, these were updates also for a LTS version that are not supposed to break a working system?

If you don't have any older kernel, just install one using

sudo apt install linux-image-5.13.0-35-generic

(the 5.13.0-35 works for me). It seems that next upgrade 5.13.0-41 is a fix.
