Lower or disable sound

Greetings, I have started playing this game and love it so far. I was just wondering if there was a way to lower the volume on the background music or mute it entirely. I have other things that I need to be able to hear on my computer, so simply lowering the master volume isn't a viable option.

Thank you in advance for any assistance.

 

Sadly, no, there isn't.
But you can always run config and tell it to run in a window.
Not quite as immersive that way, but you don't have to miss out on other things going on on your computer.
