I've sunk about 4 hours so far on this and tried all the common solution that have worked for others. I first lost my sound on upgrade to 22.04 and it's still not come back after upgrading to 22.10.
Below what I've tried and output of various diagnostic commands I've seen.
Please help!
Things tried:
Have tried the following (in some cases multiple times)
sudo apt updatesudo apt upgradesudo apt dist-upgradesudo apt autoremovesudo apt install update-manager-coresudo do-release-upgradesudo touch /usr/share/pipewire/media-session.d/with-pulseaudiosystemctl --user restart pipewire-session-managersudo alsa force-reloadpulseaudio --killpulseaudio --startsudo ln -s /usr/share/pipewire /etc/pipewiresudo touch /usr/share/pipewire/media-session.d/with-pulseaudiosystemctl --user restart pipewire-session-managersystemctl --user start pulseaudiosudo apt install libldacbt-{abr,enc}2sudo apt install libspa-0.2-bluetooth pipewire-audio-client-libraries pipewire-media-session options tried in /etc/modprobe.d/alsa-base.conf
options snd-hda-intel dmic_detect=0and also:
options snd-hda-intel model=genericsudo vim /etc/default/grub
changed:GRUB_CMDLINE_LINUX=""To:GRUB_CMDLINE_LINUX="intel_iommu=on,igfx_off"
then, of course:
sudo update-grubrebootDiagnostic commands:
