Linux audio issues on flatpak intellij build

See original GitHub issue

Issue details

Running fresh libgdx project in IntelliJ IDEA Community seems to have some issues with audio. After following guide from https://libgdx.com/wiki/start/a-simple-game audio does not work. note that fedora, by default, ships with pipewire instead if pulseaudio, and that may be the main problem.

Reproduction steps/code

Install all system updates
Install IntelliJ IDEA Community from flatpak
download gdx-setup.jar
Install java-18-openjdk and use it run gdx-setup.jar (built in jdk doesnt work for some reason)
unmark Android platform and click Generate
open the generated project with intellij, wait for setup process
Add Configuration > Add new > Application
JRE > java 17 corretto-17 (can also use jre 18, no difference)
module classpath > [name].desktop.main
Main class > com.mygdx.game.DesktopLauncher
Apply, OK
Shift-10 (Run) (The error messages appears)
follow https://libgdx.com/wiki/start/a-simple-game guide fully (The audio doesn’t work)

Version of libGDX and/or relevant dependencies

[Gdx version] 1.11.0

Taking multable tests with non flatpak builds of intellij seems that everything is working. In short this is a flatpak intellij issue, not libgdx.

Yeah from debugging a bit in discord, this seems to be a general issue with flatpack and it seems like that there’s some missing configs for it to work.

Basically from what I can see the PA client tries to connect too the PA server socket in a wrong location and you’d need to tell it to connect to the proper one. No clue how though.
