I recently installed Ubuntu 22.04 LTS and the sound isn't working in my built in speakers. Firstly it started by displaying "Dummy Output" in the system and after a couple of troubleshooting I read it now displays "HDMI output" although the laptop doesn't have it. I tried lscpi and it seems that the speakers are recognized. In ALSA the first column doesn't work. I tried pulse sound is as system. Kernel version is 5.15.0-60-generic

EDIT Heres the output for sudo lshw -C sound

Same here for 5.19.0-35-generic kernel.

I'm using 5.19.0-32-generic now as workaround.

You can use Mainline tool (installation guide) to manage kernel versions. Or just figure out if older kernel version you used to have beore update exists in Grub (pre boot screen, Advanced boot settings) and works for your case.
