No sound, Dummy output on Acer Swift 3 SF314-57G with Ice Lake core-i7
CPU

Invalid

Bug description:
[Impact]
On this machine, after booting up, there is no valid sound card, the
gnome-control-center shows a dummy output only. check the dmesg, the alsa
sof driver fails to initialize.
[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.
