From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there an app that can program audio configuration? (lemy.lol)

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. pactl for pulseaudio and wpctl for 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.
