Dummy Output Issue on Arch Linux

Hello, I'm relatively new to Arch Linux and still trying to learn. Currently, I have Arch Linux installed on my new Huawei D15 with an AMD Ryzen 5700U processor. However, I'm unable to get any sound; I'm constantly getting the "dummy output" issue. I've encountered the same problem when I tried a couple of other distributions as well. However, since I'm using Arch, I'd like to know how to resolve it specifically for Arch. Can anyone help me with this?

Re: Dummy Output Issue on Arch Linux

How did you "resolve it specifically" in those other distributions?

Re: Dummy Output Issue on Arch Linux

I couldn't resolve the issue on other distributions either, but since I want to use Arch specifically, I mean I want to solve the problem especially on Arch.

sudo fuser -v /dev/snd/*
sudo dmesg | grep -E 'snd|sof'
aplay -lL
pactl list cards

in code tags. Random guess, install sof-firmware and reboot

Re: Dummy Output Issue on Arch Linux

I assume this uses the same chip as other similar huawei models. What is the exact model of your laptop?

head /sys/devices/virtual/dmi/id/{board_vendor,product_name,board_name,product_version}

Linux 6.7 has added suppport for some of those.

It looks like Linux 6.8 might have some better logic that does not require manually adding all models?

Unfortunetly. It wasn't effective.
