No audio. PulseAudio. No analog device detected. Laptop.

Hello,

I recently installed linux on my Huawei Matebook d14 2020 (ryzen 4800H). Pulse audio does not detect an analog output for my internal speaker:

aplay -l
returns:

I can make hdmi sound work if I set it on default.pa

It also does not automatically recognize my microphone but I can see it on arecord -l

card 1: acp [acp], device 0: DMIC capture dmic-hifi-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

and adding

#load-module module-alsa-source device=hw:1,0

and restarting pulseaudio makes it visible.

Do you have any idea what's going on?

Re: No audio. PulseAudio. No analog device detected. Laptop.

Try installing sof-firmware and reboot, maybe post

sudo dmesg | grep -iE 'snd|sof'

Re: No audio. PulseAudio. No analog device detected. Laptop.

I have similiar problem with matebook 14s 2021. Headphone and speaker aren't recognize correctly. When I plug headphone, sound comes from speakers. When unplugging headphone, sound mutes. From alsamixer, I can set volume on but this is not best practice. I think huawei uptodate matebook series laptops have similiar problem

Install of latest `alsa-ucm-conf` solved the issue for me.
