Hello, I have a problem and not sure how it's happening. When my Helix sends PC messages to the H9 it first display a parameter setting (as if I moved the the knob) and then loads the preset but it is mute. I have to then unplug and plug it back to get it to work. Any advice?  thank you

What is muted? All sound or just the effect? What did you unplug and plug?
