With kernel 5.11-rc5 from that repository the problem persists, same as for 5.8.0-40-generic. The internal microphone is not shown as an input device in pavucontrol and not listed in the output of 'pacmd list- sources'. I'll attach the logs below.
I have also checked kernel 5.10.0-051000-generic from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.10/amd64/ - the problem is there too, microphone is not detected. ** Attachment added: "Output of 'pacmd list-sources' with kernel 5.11-rc5" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1912963/+attachment/5457391/+files/pacmd-list-sources-5.11-rc5.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1912963 Title: [ThinkPad E14 Gen2] Internal microphone is not detected Status in linux package in Ubuntu: Incomplete Bug description: The internal microphone is not detected when I use the stock kernel 5.8.0-40-generic: pavucontrol does not show it in the list of input devices, the applications like Zoom or Skype do not see it too. It looks similar to https://askubuntu.com/questions/1277606/internal- microphone-not-working-on-lenovo-thinkpad-e14-gen-2-amd. I tried the workaround mentioned there: switched to kernel 5.9.0-050900-generic from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9/amd64/ - and now the microphone was detected and seemed to work OK (I checked that with pavucontrol and Zoom).

I am not sure if this is an issue in the kernel, or in pulseaudio, or in some other software. Filing this bug against 'linux' package now, because the issue did not show up with kernel 5.9. Please reassign the bug if needed.
