Yep, I ran pacman -Syu on my MORPHIUS, and after rebooting, my audio no longer works at all laptop inbuilt speakers are not working, and Dummy Output is the only option showing up in the menus.
I tried downgrading linux and linux-firmware to the previous version that I found in /var/cache/pacman/pkg, to no avail.
I also tried running the audio script, that didn’t seem to do any good either.
Any ideas? The sound has always worked out of the box on this laptop for me before so I was shocked and confused when it suddenly stopped working after the most recent update.
EDIT: I installed PulseAudio Volume Control and alsa-utils and noticed that the acp3xalc5682m98357 still shows up, but it said it was (unplugged) and (unavailable). I tried plugging a wired headset into the 3.5mm jack, and it works! I tried selecting other profiles, but none of them seems to work for routing sound to the laptop speakers. This would seem to imply that the audio driver is working properly, but somehow got misconfigured so it cannot output to the laptop speakers anymore. Has anyone else encountered similar issues? Any ideas for going about fixing it?
EDIT2: For the record, my operating system is Arch Linux.
UPDATE! I managed to get my speakers working again! It seems there must be a regression in the latest version of ALSA. Downgrading the following packages fixed my system (it is probably not necessary to downgrade all of them, but I didn’t want to introduce any weird version inconsistencies)
linux=6.13.8.arch1-1
linux-firmware=20250311.b69d4b74-3
linux-firmware-whence=20250311.b69d4b74-3
alsa-lib=1.2.13-1
lib32-alsa-lib=1.2.13-1
alsa-ucm-conf=1.2.13-2
alsa-card-profiles=1:1.4.1-1
I installed the latest versions that I found in my pacman cache prior to the update I tried to do yesterday.
So, if I’m reading this correctly, I should only need to downgrade alsa-ucm-config and it should be fixed whenever the next tag is cut and works it’s way downstream to the Arch repos?
Yeah, or manually apply the fix to the current version.
I’m sorry, I don’t mean to be an idiot but how do I do that? Ok, I figured that out, and the device is now showing up, but I still don’t have any audio except a couple of little clicks during startup. I was having the exact same issue as above. I am running Ultramarine. Any advice on how to diagnose these issues from here would be great!
Update: I just got a very loud hissing noise through the speakers, it scared me half to death 
but nothing has changed aside from that.
