Can't hear audio in Unity

Is this a bug? I'm so confused.

I have some audio set to play on awake. The audio will play in the editor, but it won't play in play mode. I checked the stats and it clearly shows that the audio is playing, but I can't hear it.

Every time I exit play mode though you can hear a little something of the audio! It's infuriating!

I have restarted Unity, my computer, cleared the GI cache, removed and attached another audio listener, forced audio to play on awake via script, but NOTHING!

In another project where I had audio, the audio plays when in play mode, but for some reason refuses to play in this project.

Please help.

Here's a clip showing what I mean.
