Man, the same thing happened to me about a month ago. It was very weird, since as you say I got audio on all other applications. I tried a bunch of things and nothing worked. Finally I changed audio interfaces and the sound returned.

I use (now) a Focusrite Scarlett 4i4, connected to the laptop via USB, and then have headphones hooked into the Scarlett. Previously I was using an Audioengine D1, and had for years with no issues.
