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
