AudioListener is Inactive

I'm making a music-based game and the audio has stopped working entirely.

For some reason, the mixer isn't outputting any audio to my audio listener. The mixer says that my audio listener is inactive (see it in the image). I had set this mixer up a while ago, and had everything playing at the levels I needed, and was cycling between snapshots as the player moved around the world.

Things I've tried:
I went ahead and made sure that I've got one single audio listener in my scene, and that it's enabled.

I've also removed the audio listener and added it back, to no avail. Even tried putting it on different objects.

I didn't make any changes to the audio since the last time it was working, but I did upgrade from Unity 5.2.2 to 5.2.3...I don't know why that would effect anything, but I'm at a loss here.

 

IMMEDIATELY found the solution. Duh-doiii

Disable Unity Audio was checked on in the Project Settings > Audio. I must have done that and completely forgotten.

EDIT: What a scrub.
