Hey guys, just installed Tumbleweed on my Thinkpad X13 Gen 1.
I have the problem that i cant use the onboard speakers.
The audio device wont show up. (under windows they work)
I tried using Bluetooth in ears and they are working.

-installed missing alsa-firmware

Is the package sof-firmware installed? If not, install it and reboot.
