FLX6 - Loading new track sometimes doesn't have audio

FLX6 - Loading new track sometimes doesn't have audio. This happened like thrice during practice and there is no volume meter indicated after pressing play.

The workaround I did was just re load the track again, then it would work. I'm not sure if it's a bug during song loading or something.

I use a Dell Inspiron i5, with 12GB RAM running windows 10. Any thoughts?
