I’m on OpenSuse Tumbleweed (although I’m pretty sure I noticed the behavior on Manjaro, too).
The problem is that the volume of e.g. Firefox gets turned down for no reason. I noticed that a youtube video was quite quiet. I then checkt pavu control and saw that the volume for Firefox was set to 83%. I set it back to 100, but after the pc resumed from standby, it was at 83 again. Sometimes it’s enough to just pause the video for it to move the volume back down.
Why is that and how do I disable this functionality?
maybe ff syncs the youtube video volume to the pa slider?
It was this for me, but it only works in one direction - when turning it down. So turning down YT volume means turning down system audio, then turning up YT audio is just turning up the YT audio. Insane behaviour. There is a way to turn this off in Firefox flags (about:config). This shit also messes with your system mic volume on MS Teams.
What is the flag for this?
Closest I can find is:
media.peerconnection.enabled
This disables all the WebRTC cancer.
In chrome you can also search for WebRTC but that’s the culprit I think.
In addition I’d recommend giving this a read:

Especially comment 136
Look at the mentioned media scale flag too.

Good fucking luck.
Mozilla can’t put together a half way functional browser to save their life and lick up every enshittification doohickey that falls of the back of the burning Trainwreck that is Google.
Kinda. If I move the volume slider of the YouTube video player it also moves in pavucontrol automatically. But when I move it to 100% in YouTube it’s only 83% in pavucontol
