Do you know how to add a kernel parameter to the default grub file and update grub?

sudo nano /etc/default/grub

add to the end of the default grub command line

snd_hda_intel.dmic_detect=0

Example: GRUB_CMDLINE_LINUX_DEFAULT=“quiet loglevel=3 snd_hda_intel.dmic_detect=0”)

Then save with

ctrl + o enter

close with

ctrl + x

Then update grub

sudo grub-mkconfig -o /boot/grub/grub.cfg

reboot

Edit2:
This may or may not work for your issue but worth a try. If it doesn’t work. Just remove what you added the same way and update grub again.

Is audio working currently? Some of these Intel audio chips require sof-firmware also in order to work. I think this may be one of them. Maybe?

Edit: Other then this you’ll have to look at the Arch wiki

Thank you so much! Editing /etc/pulse/default.pa worked.
