For some reason I can no longer see my mic in the sound app / config application. The selection box is empty.

Internal microphone. Lenovo X1 rev 9.

enter image description here

However this lists a device:

Why is the system not recognizing this microphone?

What version of Ubuntu are you using? The output you show tells me it sees the sound hardware but does not give a clue why the mic is not working. You also have not said how the mic is attached. 3.5, USB or some other method. Please add the details to the question.

The legacy intel drivers will probably never support this chipset fully.

Here is how I finally fixed this:

  1. Replace pulseaudio with pipewire. Follow this howto. https://linuxconfig.org/how-to-install-pipewire-on-ubuntu-linux
  2. Install the firmware-sof-signed package. Replaces the old intel drivers.

Verify the outcome (pulseaudio replacement):

I now have fully working microphones (plural since this laptop have several). The output devices work as they used to earlier.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
