I guess the problem is that the USB messages that the USB clock driver (sound/usb/clock.c) is sending don't get a reply in time.

Do I understand correctly that audio usually works, just about once per week the above mentioned lines are found in the kernel log and then it doesn't work? Do these messages happen during boot? Or when you start using audio? Does a reboot help then? Or replugging the audio hardware (or is this an internal USB-C device)? > Is there something else to help finding out, where the issue is > located, or even rule out a software issue?

Does the bookworm kernel work on this machine? You could try that then. Or the Ubuntu kernel might be worth a try. Best regards Uwe
