Welcome

I have a problem with sound, here is some history of it:

2 years in the past the sound worked perfectly. Then it stopped, I needed to install sof-firmware package. From about 3 months it started not working again. Every sound device is detected, but nothing really works. I tryied many things but nothing helped.

For arch linux specific problems i found https://bbs.archlinux.org/viewtopic.php?id=251153

But i cant easily downgrade such a low-level package

any ideaas?
