PCI/internal sound card not detected

[Jesko]

Two days ago the audio of my laptop was still working fine. Between then and now I did a kernel and gnome-shell update (those are the ones I remember). Now my sound settings do not show any devices beyond the dummy ones.

I have Ubuntu 19.10 on my Thinkpad X1 Yoga and I've tried these https://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/ and https://help.ubuntu.com/community/SoundTroubleshooting things

Here are some maybe relevant packages

Ok, I've downgraded to kernel 5.3.0-40-generic and the audio works again.
I've also noticed that in 5.3.0-42 I cannot wake my laptop after suspend.

[Hui Wang (hui.wang)]

@Jesko,

-42 has a regression on sof audio driver, please wait for the coming -43 kernel.

thx.

[Jesko (jeskowastaken)]

I'm now on -45 and the issue still exists

[Hui Wang (hui.wang)]

some fixing patches are in the 5.3.0-43, but somehow they are not in the 5.3.0-45. I just checked the 5.3.0-46, those patches are in the -46 kernel.

So please use -43 kernel or wait for -46 kernel.
