There some audio issues, when you play some native games that uses FMOD. And there is no Pipewire option in in-game audio settings.
After some time spend to "research", I found out that this may be related with pipewire-alsa module.
Project Zomboid - on first run there can be sound, but there is no way to change volume. Next game start will be without audio, and there will be nothing in in-game and system (kde) audio settings.
Euro Truck Simulator 2 - If you want to have sound you must close all apps that use audio otherwise no sound in ETS
War Thunder - just no Pipewire option in settings
Being curious I installed Garuda Linux.
And there was no issues with these games also there was Pipewire option in in-game audio settings.
