I sometimes play games and also open my music player, but the sound from the game drowns out the music, so I need to go into the sound mixer on KDE and manually lower the game’s volume every time.
I was wondering, is there a way to do this process automatically? As in setting up conditions like “if music is playing (some MPRIS API?) then lower all other apps’ volumes)”, maybe even crazier “if some app is outputting voice then set its volume back up and lower music app’s volume or pause its playback altogether for some specified timeout that keeps being refreshed for as long as voice is heard”.
I imagine the latter is a bit of a dream, but maybe for the first, even some quick sound profile selector would go a long way, say switching from “normal profile” to “background music profile”, etc. which specify preconfigured volumes for those apps.
Is that a thing?

The details depend a bit on the audiostack of your distro, but they all have a cli program with which you can change inputs/outputs and volume; e.g.
pactlfor pulseaudio andwpctlfor wireplumber.You’ll need a mechanism to find your triggers (I create a firefox tab with youtube/spotify, I have a music player active) and then you can act on it.
Detecting voice in an audiostream is probably technically possible, but that sounds pretty hard to setup.
So what I’m getting is that I would have to come up with something myself, right? I mean that would be super cool to do, but I don’t have the time to put into that, unfortunately
Yes, a quick web search later I haven’t found a readymade solution.
Setting the volume for specific outputs is not very hard, so maybe a middleground solution is to have two shortcuts. One for “game mode” and one for “music mode” or whatever.
Pulseaudio should have hooks
# cat /etc/pulse/default.pa load-module module-switch-on-connect load-module module-exec load-module module-exec arguments="path/to/your/script.sh %s"(where %s resolves on trigger to the name of the sink added)
Your script.sh should then match the first argument to the name of the sink you want to control, and then run
# path/to/your/script.sh if [ "$1" = "THESINKIWANT" ]; then pactl set-sink-volume $1 40% fiI’m fairly sure you can do this with Wireplumber hooks. https://pipewire.pages.freedesktop.org/wireplumber/design/events_and_hooks.html
This is the architecture though, I’m asking about an application that can interact with it
I found this software a couple of days ago. Not sure if it will really help with your first problem 😆 because I’m still figuring it out myself. But looks promising. https://github.com/wwmm/easyeffects
If you find a way to do this, it would be cool if you can share it!
Will do, hopefully there is one
There is a great video on that in German
55 minutes? Uhm, could you tell me the relevant section of the video, please?
No not really
Why so irritable? I’m just asking, I don’t even know German, I thought since you knew the video already, you could point me in the right direction, rather than me having to sift through it all while also passing it through a translator to hopefully (because I don’t know how well youtube’s auto-translate feature works) find the information I’m looking for in the whole presentation
The app is called “carla” and is a plugin host for jack plugins that works with Pipewire
this is high level trolling, kudos sir
Hahaha wasnt meant like that

On a quick skim I don’t see a way on it to set volume profiles, let alone program behavior based on certain events, is there some menu I might have missed?
