The problem was already reported and resolved here (remove the space from the link to view):

`https://github.com /ValveSoftware/steam-runtime/issues/346`

I think for now we should just put a warning in the Wiki (on the FAQ and manual install instructions) and the installer, so Linux users can take actions themselves if necessary.

TODO:
- Write up a short warning message/how to fix issue
- Add FAQ item
- Add warning to manual install instructions
- Add warning to installer
- I'm assuming this applies to the Question Arcs as well? but not sure

I guess technically the new ponscripter executables might fix the issue, if we ever go that route.

Das Issue betrifft die Ergänzung von Warnhinweisen in der Dokumentation und im Installer für einen bekannten Konflikt mit einer Linux-Audio-Bibliothek. Zuerst sollte das verlinkte GitHub-Issue (ValveSoftware/steam-runtime#346) gelesen werden, um das Problem und die Lösung zu verstehen. Anschließend sind das Wiki, die FAQ, die manuellen Installationsanweisungen und die Installer-Skripte des Projekts zu lokalisieren, um eine prägnante Warnmeldung einzufügen. Es ist zu prüfen, ob dasselbe für die Question Arcs gilt. Die Platzierung und Formulierung der Warnung ist zu überprüfen.
