I hear something...but not the music.

New install, imported music library, created queue. I have two songs loaded, one on each deck, and when I start playing deck 1 I hear this distorted scrambling sound, but not audio of the music. I keep toggling the crossfader, the headphones, and have verified split output in audio settings.

No song audio from built-in laptop speakers (I do hear other Algoriddm and system sounds, other apps play fine)
No song audio from headphones
No song audio when using Griffin imic audio interface (and I hear other apps fine)

Platform: Windows 10

What should I try?
