maybe someone already figured that out, I found some topics regarding hissing noise on mic. But none of the sollutions worked and well external microphones, BT-Hedsets, Usb-Audio devices seem to work.
The internal mice worked on the same machine using Ubnt. the machine came with as well as manjaro linux. It actualy works runing the installer ISO.
Si i asume it might have something to do with the Pulse-Alsa-Hardware-Chain.
Linux spitz-3 5.10.82-1-lts #1 SMP Fri, 26 Nov 2021 10:51:51 +0000 x86_64 GNU/Linux
I run a minimal KDE/Plasma setup
Anybody any idea?
Tnx And Regards
