Music doesn't play when you open Premiere Pro (Beta)

I have a weird thing going on in my project. I'll have a song selected, drag it into my timeline, remix it to the appropriate time lenght, be happy with it, close it, reopen it. Now I can't hear anything. I'm adjusting my volume/gain, making sure I didn't click any box, but still nothing. Anybody run into this issue as well in Beta?
