Title:
No audio with kernel 6.2.0-26-generic #26~22.04.1-Ubuntu
Status in linux package in Ubuntu:
Expired
Bug description:
Hi.
Audio playback sometimes fails with kernel 6.2.0-26-generic
#26~22.04.1-Ubuntu (the audio just doesn't play). Rebooting the system
a few times makes it work again and it looks like it either works
perfectly after some boots and not at all on other boots. I see this
dmsg when it fails:

I have tried several programs and I see a similar error message with
all programs i.e. "INFO: task XXX:1234 blocked for more than XXX
seconds."
I have tried different sound cards, same problem.
I have tried other operating systems, it looks like it only happen with Linux.
3) What you expected to happen?
Audio should play.
4) What happened instead?
No audio is playing.
