Comment 836 for bug 1958019

I am running an 14IRP8 (Yoga Pro/Slim 9i), specifically this model (https://psref.lenovo.com/Detail/Yoga/Yoga_Pro_9_14IRP8?M=83BU0024AU).

I have the laptop running Ubuntu 23.10 and I run mainline kernels from Ubuntu. I have tried almost every recent kernel build up until 6.8-rc5 today (I had read that 6.8 was supposed to fix this issue). Audio is still running only the tweaters, zero bass.

I've tried many things, notably the snd.conf (options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin) to no avail. Also tried noble's firmware-sof-signed package, manually tweaking the amixer configuration.

Thanks!!
