For me the solution was to install the SOF firmware binaries from here: https://github.com/thesofproject/sof-bin

Specifically:

  1. Clone the repository: git clone https://github.com/thesofproject/sof-bin.git
  2. Change to directory: cd sof-bin
  3. Follow: https://github.com/thesofproject/sof-bin#install-process-with-installsh (for me v2.2 worked)
sudo mv /lib/firmware/intel/sof* some_backup_location/
sudo mv /usr/local/bin/sof-*     some_backup_location/ # optional
sudo ./install.sh v2.2.x/v2.2
  1. Reboot

After this the sound output as well as the microphone were working (Ubuntu 23.04, Lenovo X1 Gen8)

Note: Make sure that the snd_hda_intel.dmic_detect=0 or snd_intel_dspcfg.dsp_driver=1 settings are not set in GRUB_CMDLINE_LINUX_DEFAULT or /etc/modprobe.d/alsa-base.conf. Otherwise the sound may work but no microphone input.

in my case the kernel driver was using the snd_sof one instead of the snd_hda_intel one, but maybe this fix will also work for you.

try adding this to the alsa-base.conf:

options snd-hda-intel dmic_detect=0

and of course reboot afterwards

  • Having exact same problem, this did not fix it – Leo Feb 18 '23 at 21:53

    This fixed sound issue for me, but this option disables mic detection completely. Not a good solution. – igor May 24 '23 at 14:52
  • I had an issue (on PopOS, Lenovo X1 9th Gen) where output sound worked, but didn't find the mic/input device. When I removed this line, the mic started working. – askvictor Aug 09 '23 at 04:41
