Is other audio or sound effects playing? Could it be turned off in the in-game settings?

Everything works, except the music

You're on a Windows system, correct? Can you confirm that it behaves the same when the music setting is toggled between off/quiet/normal in the game options? In other words, does it not play when set to quiet? When set to normal? Does toggling the music on and off have any effect?

I am on Win10, yes. I have toggled everything you told me to, it does not effect the music playback at all

Have you seen this on any other games? Is there anything unique about your soundcard?

This is the only game that does not work, I have a basic, integrated sound card. No other games have errors like this

@TheRealMattKain
i got a different problem,
If i start this Game, it starts in Windowed-mode and the Sound are correct.
If i change the settings to Full-Screen, Sound dissapears, Music comes back after a short time (5 sec.) and only the music is playing. No SoundFX like Boxes and Kicks. even Rage sound dont comes trough.

any ideas?
