kSince first getting the notebook, both internal speakers and mics were non-operational, and this issue sprang right from missing support for the ALC294 in the kernel. A report was filed and I'm using alc294-sound-patch.fw from the comment on that report. An update to the kernel did fix output playback for me but did not fix the mic.
Dumping some outputs:

I looked at Internal microphone not working section but the catch did not leave any effect by enable_msi=1 to snd_hda_intel.
I'm exhausted of things to possibly try out, not sure if this has to be fixed by the kernel.
I suspect I might have a misconfigured sof-firmware package, which is my last resort to getting output from the mics. I'm tired of using external microphones for appointments doctors or other video calls. Need help fixing this!
