I installed Ubuntu 22.04 LTS on my laptop and while everything works great, I have no sound on my computer.

For me the solution was to install the latest Sound Open Firmware (SOF) 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 output may work but no microphone input.
