Built-n laptop speakers stopped working

I did a reasonably big update of packages with pacman -Syu last night (113 packages or so) and today I noticed that my laptop speakers stopped working. I searched the forum and confirm from what I read in another thread that it’s not a hardware issue because they work fine off a live usb of the same manjaro DE.

The bluetoothctl still works no problem it’s just the built-in laptop speakers for some reason. Fortunately since I mainly use the bluetoothctl nowadays this issue isn’t urgent but would be nice to get fixed without having to do a reinstall since I’m not in a position to do that at the moment.

Possible cause: when I did the package updating my screen went black and then came back. I had to reboot and run pacman -Syu to finish the upgrading of packages. Also when I first ran that command I the first time had to manually confirm switching out a few packages. (no I don’t remember their names sorry)

Side joke: I’m glad the updating caused this issue instead of wiping and rewriting the file where I blacklist pcspeaker. LOL That would’ve been very unpleasant to discover despite the fact that it’s much easier to fix.

Oh almost forgot here’s my inxi -Fx output

I think I found the possible issue but I don’t how to fix it. After posting the inxi stuff I wondered if there was a difference in the audio info from the same command off a usb which I downloaded today and there was. The kernel version on my main install is 4.19.23-1 and the usb was 4.19.2-1 However I’m starting to think the kernel might not be the issue because I just tried downgrading to all available kernels (4.19.20 4.19.16 and 4.19.14) and there was no change although all available kernels are newer than the one on the latest live iso so I can’t rule it out for sure.

Final Update

Decided to use my snapshot from timeshift to restore my system but doing so completely broke it so now having to reinstall the system and using live usb to back stuff up at the moment.
