Problem Description:
Hi, I noticed that sound is not playing anymore since upgrading to 25.10. I can see a sound bar moving when selecting an audio device in the audio menu and bluetooth also works fine, just no sound from the laptop speakers. I remember using the laptop speakers in August when I was on either 24.10 or 25.04

The kernel module seems to be working, although lsmod does not show the exact name ( sof-audio-pci-intel-mtl vs snd_sof_pci_intel_mtl)
What I’ve Tried:
I found a similar question being asked here: No sound on fresh Kubuntu 25.10 , but reinstalling the modules did not fix it for me. I have also tried loading the specified kernel module but that has resulted in the following error:
sudo modprobe -v sof-audio-pci-intel-mtl
modprobe: FATAL: Module sof-audio-pci-intel-mtl not found in directory /lib/modules/6.17.0-8-generic
Thanks for anyone having a look, hopefully this is something simple.
