I also tried the two changes above to 6.7.6, it took a bit for me to work out how to compile a custom kernel in ubuntu (easy once you know). Mine is a slightly different 14IRP8 device Yoga Pro rather than Slim Pro (same underlying hardware).
Alsa-info -> https://alsa- project.org/db/?f=3adac42b53db18376ea17cd5ab008c247a4039a5 Applied the latest firmware to /lib/firmware from https://gitlab.com/kernel-firmware/linux-firmware.git (branch main). Confirmed no options are now required, overall sound is considerably better, volume works, headphones also work. Subjectively audio doesn't seem quite as good as in Windows, where the bass seems to get dynamically adjusted depending on the volume (maybe some fancy DSP effects, not sure - I am only guessing). Either way, it is now light-years better than what it was before the changes.
