I think its time to get rid of this annoying background sounds, that i have since the big Plasma 6 update. 
I was looking at notification already, but i can’t find a way how to get rid of this background sounds from Firefox Window changes.
It only plays this soundfiles when i Close or Maximize Firefox… reduce or minimize has no sounds and it happen only to the Firefox Window.
Anyone have a idea, how i can mute Plasma/Firefox for this actions?
Hi @Kobold,
I don’t have any notification sounds enabled. (Not to mention, being hard of hearing would have made them pointless anyway.)
So all I can recommend if you check this:
Thank you for the info @Mirdarthos,
unchecked “Enable notification sounds” works to mute the Firefox sound… but it also disable all the other Notification sounds that i like 
I would expect this soundfiles are linked in: system settings>notifications>applications specific settings…
There are all kind of theme sounds linked to the applications, but strangely its not showing anything on Firefox.
Unfortunately I have no idea how to target a specific application. Maybe there’s something in Window rules.
There is a short thread on Arch forum that could help you

Thanks for the link:
There was someone posted a command:
ffmpeg -f lavfi -t 1 -i anullsrc=channel_layout=stereo:sample_rate=48000 -y /tmp/silence.ogg
Is this command doing what i think? does it create a empty .ogg file?
I ask this because i don’t want to execute a command that i can’t rate and i don’t want to change system settings with this command.
A empty .ogg file is exactly what i need to replace it with the annoying soundfiles in /usr/share/sounds/
Yes, it creates file in /tmp containing 1 sec of silence
It is worth remembering that /tmp is recreated on boot so when the sound is to replace another - it will be a good idea to save it somewhere permanent.
I also noticed the bad behavior when Plasma 6 released, I had some system sounds that were OK, then I enabled one of the sound pack, and there was these annoying sound effects I didn’t want, then I disabled the sound packs but it indeed disabled everything and didn’t get back to how it was. I can’t recall how I did it, but I eventually made it like it was initially with some sound effects but not all for everything possible. I did not mess the the files in the sound packs.
Of course he just used the tmp folder only as a universal option for everyone’s system. The goal is to copy the files to replace the soundpack .ogg files
Hopefully your memories coming back soon, i can wait a few days… till i mess around with the soundpack.
Here is how it is currently in the System Settings for me:
But I think if I click another sound pack and Apply, then go back to the FreeDesktop sound pack and Apply, it will revert to ALL sound effects enabled (can’t guarantee but I think in my troubleshooting this is what happened back then).
//EDIT: I find probably relevant references to “freedesktop” in these files:
~/.config/xsettingsd/xsettingsd.conf
~/.config/gtk-3.0/settings.ini
~/.config/gtk-4.0/settings.ini
//EDIT2: I do not see the sound files window-maximized.ogg and window-minimized.ogg in /usr/share/sounds/freedesktop/stereo/ so maybe try to enable the FreeDesktop sound pack and see. Reboot afterwards to make sure there is no residual sound/settings after applying FreeDesktop sound pack.
No such sounds here.
Using ‘yaru’ sound theme.
