How to Restart Microphone Subsystem?

Support Sound
1

I occasionally record in Audacity, and I’ve encountered an issue lately where the recording from the microphone sounds like its in fast forward.

Any recording done on the system sounds strange, but dosn’t after a reboot. This issue usually occurs at random after some hours that the system has been on.

Is there some service that I can restart instead of having to reboot the entire system?

I’m on KDE Manjaro:

Didn’t fix it unfortunatly :smiley:

Both Kdenlive voice over and Audacity still have strange issues. OBS does as well :smiley:
