I cannot hear any in-game music, I can only hear the announcer and sound effects. Master Volume, Music Volume and Sound Effects are all high.

Tried to download a music mod to see if it would work, all Mod sound effects/announcers work, just not any music.

It wasn't always like this--I played MoD when I first bought it last year and all was well, and about two weeks into loving it, the game suddenly wouldn't boot up. After a HUGE ordeal, uninstalling/reinstalling, having to work through system files, I took a hiatus because it wore me out...considering a refund, as I always seem to experience issues one way or another.

I can hear other games' audio/music/sound effects perfectly on Steam and off Steam.

Everything else on PC is normal, Youtube/Hulu/Netflix all work, sound is perfect.

I don't really know what else you'd need, let me know if I can answer any other questions at all.
