Hello gentleman!

I have the Fedora 38 Workstation. And all works perfect, but one day ago my microphone started to record strange alien sounds.

I’ve searched some information from commands:

arecord -lL

**** List of CAPTURE Hardware Devices ****
card 0: Camera [A4tech FHD 1080P PC Camera], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 2: Generic [HD-Audio Generic], device 0: ALC1220 Analog [ALC1220 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0
card 2: Generic [HD-Audio Generic], device 2: ALC1220 Alt Analog [ALC1220 Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

ALC1220 is my recording device (the rear microphone).

When in GRUB I load the Fedora 37 the microphone works perfect.

Actually, I’ve noticed the strange thing in Audacity: one second there is equal to twelve seconds in real-time…

The test recording is HERE.

Should I purge pipewire and install it again?

I’ve run that command:

sudo dnf downgrade pipewire --allowerasing

and have rolled back to the pipewire-0.3.67-1.fc38 packages.

Aliens went away!!!

The problem returns…

I’ve excluded the pipewire package in dnf, but after some time the problem returns.

After rebooting the microphone works normal.

Hello! I have to run any sudo command in terminal after OS startup. Even if I skip the password the microphone will work normally.

I have the same problem on f39 and f40, so I’m going to create a new thread.
