Do you have full volume sound? I have a similar model (https://psref.lenovo.com/Detail/Lenovo/Lenovo_Slim_Pro_9_14IRP8?M=83BV0002US) and had to do a few things to make the amplifier work in the first place, but I still don't have any bass.

To get sound on linux 6.7 I had to update the firmware files and use `options snd-sof-intel-hda-common hda_model=17aa:38be`, which had a different effect to alc287-yoga9-bass-spk-pin (not sure why). I described with more details at https://github.com/PJungkamp/yoga9-linux/issues/11#issuecomment-1899400594

I didn't try a lot on 6.8 but my current config doesn't fix the bass there too.
