I've been using audio on a ASUS Zenbook for about 2 years now without problems. I recently switched from kernel 5.15.70 to 5.15.71 - and suddenly I have severe audio problems: playback or record stops after a while, or it stops working when I plugin my headset. Really annoying during web meetings ;-) I switched back to 5.15.70 and it works. I saw several other issues with ASUS notebooks here, but in this case this seems to be related to some changes from 70 to 71.

It'd be great if performed regression testing using git bisect: https://docs.kernel.org/admin-guide/bug-bisect.html There are actually very few ALSA related patches between these two kernels so you may as well try building by removing them one by one.
5.15.0-71-generic sounds like a vendor kernel that might contain many patches (and might not even be based on 5.15.71). If it is, report the problem to your verdor. If not: 5.15.71 is old, the bug might have been fixed already, hence please try the latest 5.15.y release; and check if things actually worked with earlier vanilla 5.15.y. You need to clear the situation up, otherwise the Linux kernel developers will likely will ignore this report.
It is a ubuntu kernel and the latest that is shipped with Linux Mint 20.3. I tried compiling a newer kernel yesterday (for the first time in my life :-)) but got so many errors, that I stopped after spending some time fixing the first few... I really would like to try the current kernel. I guess somewhere in the internet there is documentation how I could use another kernel not included in my distro? Or I could boot from an USB of some distro that has a newer kernel included. Any recommendations?
WRT git bisect: as long as I don't manage to compile any kernel, I can't help with bisect (which I didn't use yet) I fear
I also postet the issue at launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2019013
(In reply to Peter from comment #3) > I really would like to try the current kernel. This might help: https://docs.kernel.org/next/admin-guide/quickly-build-trimmed-linux.html If something doesn't work on your distro, let me know (direct mail is fine).
