Public bug reported: New focal installation on a new Acer Swift 3 laptop with core i7-1065G7. No sound detected, KDE/pavucontrol shows Dummy output. External headset also not detected.
I've googled around and tried to reinstall alsa and pulseaudio, tried alsa force-reload as well. Nothing helps. With snd_hda_intel.dmic_detect=0 speakers start working but microphone is not detected. External headset detected with both headphones and mic. I use this as a workaround for a time being. I've checked https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860697 bug. It is closed and use recent kernel and firmware but it does not fix my issue.
