I noticed today that the sound/music in a game I had running in the background was playing when the screen is locked. I tried muting the sound, and turning down the volume, which will mute the sound for a short time before it's back again. This behaviour will only occur when the screen is locked. As soon as I unlock it, it is muted like it should be.

Any ideas what may be causing this issue?

I had a similar issue, and solved by:

Comment line load-module module-switch-on-port-available from /etc/pulse/default.pa and then restart pulse with pulseaudio -k

  • This did not solve the issue in my case (Ubuntu 22.04.3 LTS). I have the same problem when my laptop is connected to monitors through a docking hub. Nearly blew out my headphones and my ears because of this issue in Ubuntu. – AsgerHB Aug 29 '23 at 09:22
