Suddenly Can't hear audio while inside GM drum map

Hey! I use the GM drum map editor with ezdrummer, suddenly the audio for the rest of the tracks is gone when working inside the drum map. I’ve made sure all drivers and software are up to date, anyone have any idea what I might be doing wrong?

Any instrument used with the drum map has the same effect, so it’s not specific to ezdrummer.

Figured it out. The Solo editor all the way up in the very top left corner was activated. I didn’t know that even existed.
