No sound with 6.0.3 #31
Description
No sound with latest from https://launchpad.net/~tuxinvader/+archive/ubuntu/lts-mainline (6.0.3-060003.202210220529). Downgrading to 6.0.2-060002.202210150929 brings sound back.
Output of inxi is the same with 6.0.3 apart from kernel version string.

The issue is exactly as described here: https://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ (no hardware device, only dummy output/input) and the only option which almost helped was to add options snd-hda-intel snd-intel-dspcfg.dsp_driver=1 to /etc/modprobe.d/alsa-base.conf and force-reload alsa — this felt back from sof-audio-pci-intel-cnl driver to snd-hda-intel and brought back sound output, but no mic. Had to downgrade to 6.0.2 where there's no such issue.
Please let me know whether I should provide any additional info to help you figure the root cause.
Thanks.
