Dear all,

I just started a video conference and the microphone was not working anymore (it was working three days ago). In the speaker/microphone menue, the microphone is not visible anymore.
In the KDE audio settings, the microphone was not visible anymore. First there was the option “show inactive devices” and my mic was shown as inactive device. After some time checking it again and again with different devices, this option was not available anymore.
I also tried a bluetooth headset (plantronics) or a roomspeaker (jabra): speaker fine, no mic function

My computer: Lenovo Thinkpad Carbon X1 Gen 9 (Tiger lake), Audio: Inter Tiger lake.

Has somebody an idea why the microphone abilities disappeared?

Best,

Michael

To start with show what is reported by ALSA…

arecord -l

and pulseaudio (assuming active)…

pactl list sources

Also, the hardware details themselves. For that you can use inxi (install it first if necessary).

Update it with

sudo inxi -U

then

inxi -Axx

Dear deano_ferrari,

thanks for the answer!

Dear all,

today, there was a new kernel, ALSA and pipewire update. And after a reboot, the mic is working a again.
Sometimes patience (I would need more of it ;-)) and trust to the Linux community is solving the problem.

Best,

Michael
