Acer aspire5 N20C5 no sound kernel 6.6 and Intel Tiger Lake-LP Smart Sound Audio

I have (partially) solved the issue. No microphone but at least sound,

Not sure which of these is critical but I would do them all.

  1. upgrade kernel to 6.8
  2. load 2.9 sof-bin from repo (NOT from AUR as it is not latest)
  3. make sure pipewire is enabled and add some lines to alsa-base.conf in /etc/modprobe/d

details.

  1. upgraded kernel to 6.8 using manjaro settings. Make sure your boot loader is loading this kernel

  2. see here

and then download release here and run install.sh

  1. see here
    [SOLVED] ALSA does not recognize my soundcard. Intel Tiger Lake Audio / Kernel & Hardware / Arch Linux Forums

and make sure any other sound related kernel options/modules you might have set are disabled/removed.

systemctl --user --now enable pipewire pipewire-pulse wireplumber

Also I had to add this in /etc/modprobe.d/alsa-base.conf

options snd-hda-intel dmic_detect=0
options snd-hda-intel index=0
