Edit 2:

Just my chance I found the error. I am using an external monitor which is connected via Thunderbolt to my monitor which transfers power, the video and audio signal. For windows (and other Linux distros such as Manjaro) I can just leave my laptop closed and only use my external monitor, but Ubuntu ONLY seems to recognise the laptop speaker when I boot with the laptop "physically" open.

Edit:

I do not know what changed, but after a few restarts the problem came up again and I am at the start again. I tried the force reinstall, but still no good. Very weird behaviour.

Old

For anyone on an old ThinkPad:
I am working on a Lenovo ThinkPad X1 Yoga 4th Gen and installed the latest Ubuntu LTS (22.04 at time of writing). I tried the options above but what seemed to help was:

Have the blacktlist as mentioned above AND also forcefully reinstalling what martinseener mentioned above.
