Have kind of a weird problem. I upgraded to Plasma 6.1.4 recently (on Gentoo) and it set the new Ocean theme for system notification sounds, which is find. However, every time my monitor goes to sleep and wakes up it plays a notification now that I find quite excessive.
I want to disable that, but… I can’t figure out how. I looked under System Notifications and can’t find find anything matching those sounds or description. I looked at the event notifications in Application Settings and can’t find anything there, either. I then played every ocean theme sound in /usr/share/sounds/ocean/ and can’t find the exact sound that’s made when my monitors sleeps/wakes. Similar, but not identical. I even thought my monitor itself might be generating these noises as I got a new monitor around the same time as the upgrade, but confirmed this is coming from the system.
Where/how are these sounds defined? How do I disable them? I’m really at a loss here. Disabling system notifications altogether makes it stop, but I like the notifications elsewhere.
Edit: Never mind, I finally figured it out. My monitor was, for some dumb reason, disconnecting it’s USB hub from the computer everytime the display went off. So it’s the device disconnect/reconnect sound I was hearing, which didn’t match up with the samples I listened to because it’s firing two sounds each time the hub disconnects and reconnects.
Weird, but at least got it identified.
