No sound after today's update on Lenovo Legion 7i

Hello, after today’s global update, I lost sound on my laptop Lenovo Legion 7i. I thought something broke the fix on the kernel that was provided in https://bugzilla.kernel.org/show_bug.cgi?id=208555, but even after upgrading the kernel to the newest one 5.16.2-1 I still got no sound from speakers. I get the sound if I use headphones which reminded me of the issue that I had before the fix above came in.

I think that the last update of manjaro-pulse has physically damaged my speakers because when switching to my other systems windows and Ubuntu there was no audio neither.

I got the same issue. How to solve this?

same issue here, but speakers working fine in windows

Hello again. So after trying many solutions like switching to pipewire, resetting the bios setting, nothing worked. I made sure that it is not a software issue by running my other systems Windows and PopOS that were installed next to Manjaro and that had working speaker audio beforehand. They was no sound coming from speakers as well even though I didn’t touch and they also had drivers working properly. So I just contacted Lenovo to send the device to a repair center and probably replace the faulty speakers.
