Grand 3 Audio dropout

I have been getting audio dropouts when I import a midifile and try to play it back. The audio is set correctly and the keys on the keyboard are moving, just no sound.
vs 3.1.0

Ok, it turns out the volume knob is zeroing but not showing its at zero physically on the knob itself. In order for me to get it to work I have to click on it when the song is in play and then after I replay, it zero’s out again but the knob still shows full volume. Sounds like a glitch in the update since I didn’t have this problem before. Very frustating
