I don't recall having this issue before, as I've been able to use Zoom on my laptop with internal microphone. I haven't done so often though, so can't pinpoint which update may have broken my internal microphone.
I have always used Ubuntu 22.04 LTS and it's been great. However when I go into the sound settings and lookup my input devices, the device if I recall correctly, "Digital Microphone" is no longer present. All I see is "Analog input - built in audio" which is my 3.5mm socket on the laptop.
As I needed to fix an unrelated annoyance, I felt it was time to format/reinstall. I installed 22.04.3 LTS and still face the same problem on a fresh install. Now I'm really unsure what has borked the audio. Output is still ok though. See my lspci below;

Has anyone else had this issue with this particular laptop? I've notice similar issues on previous ubuntu versions, and previous gen thinkpad X1s, but I've not had this issue prior. I'm at a loss to what it could be.
EDIT: There's also an audio output issue. I hadn't noticed i much as I've had the laptop on a dock and use the dock's audio/stereo system for sound. When not docked, the internal speakers only have one volume: max. No mantter how many steps up or down you've turned the system volume, it stays maximum, unless you turn it to 0, whereby it's muted.
This was NEVER an issue. To find that issues are with the audio, and persisting through nuke/reinstall, I suspect maybe a bad firmware update? That's literally the only change persisting on my system since the time it worked OK.
Thanks in advance!
