(K)ubuntu 22.04 - Microphones seem to be muted

jp flag

I've got a problem with my new computer (Fujitsu Lifebook u7412). I first installed Ubuntu 22.04 and later changed to Kubuntu 22.04. On both, I've got the same issue. My microphones don't work. All my devices are recognized, but the microphone is still muted. (At least I didn't get any input signal from my various inputs). I have a mic symbol on my keyboard, but nothing happens after pressing the button.

I found some solutions with adjusting the codec. But

cat /proc/asound/card*/codec* | grep Codec

gives

Codec: Realtek ALC257
Codec: Intel Alderlake-P HDMI

Under https://www.kernel.org/doc/html/latest/sound/hd-audio/models.html I found 3 possible codecs, but none of them work.

Any suggestions to fix my issue? Thanks!

EDIT:

My bluetooth-headset is working. What is the problem with my wired connections...?

I sit in a Tesla and translated this thread with Ai:

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.
