Check ALSA Settings: Open a terminal and run alsamixer to check if the sound levels are correctly set. Make sure none of the channels are muted.
Verify Kernel Modules: Ensure all necessary sound modules are loaded. You can do this by running sudo modprobe snd-hda-intel and sudo modprobe snd-sof-pci-intel-mtl.
Update System Packages: Update all system packages to the latest versions using sudo pacman -Syu.
Configure GRUB: Edit the GRUB configuration file to disable dmic_detect for snd_hda_intel.

sudo nano /etc/default/grub
Change the line in /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet snd_hda_intel.dmic_detect=0"
Then update the GRUB configuration with

sudo grub-mkconfig -o /boot/grub/grub.cfg
Enable and Start Services: Enable and start the necessary services with

systemctl --user enable wireplumber systemctl --user start wireplumber
Reboot: Reboot your system to apply all changes.
