This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] Backport a patch from upstream, after applying this patch, the sof driver will not fail anymore even the codec driver is hda_generic [Test Case] A couple of users already test this patch on their machines, after booting up, there is a valid sound card, and could output sound from output devices. [Regression Risk] Low, this is cherry-picked from upstream, and this just adds a new kind of codec (generic) support, and a couple of ubuntu users already verified this patch. 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.
