KDE random audio changes (Media Controller)

Help
1

I use the media control to change firefox audio separately from my main speakers, but it randomly changes the audios volume. Sometimes it changes by 1% or other times it jumps to 100% like if it was a jumpscare. Any suggestions on fixing this?

Can you tell me wich media controls misbehave (how to reproduce?) Or post a screenshot how you change your volume?

So far its just firefox, I use a hotkey to change the media audio. I haven’t noticed any other application doing this.

The volume level in the media controller applet is a property of the MPRIS (the standard interface for media controls on Linux) player.

I’d suspect that random changes in the volume there come from the application (i.e. Firefox) itself

So I think you are correct, Firefox is the issue but only when watching/listening to YouTube videos. I’ve used Vivaldi and used firefox with other media players (hbo, disney plus, etc) with no problems. I honestly don’t know why youtube is doing this. Thank you for responding.

Try and see if the behavior persists with the normalize audio feature enabled and disabled. It is called “Stable Volume” in the video settings.
