Quoted from Dizzyjw23:
I got home and this fixed it!! soniczone I can’t thank you enough! I was searching through every forum I could find for an answer. Appreciate you taking the time to help me.
I just got a new replacement sound board and I don't hear that humming ship idle sound(I believe that's what you're describing).
I'm hoping a setting change fixes it. I wasn't aware that it was something you could change.
Thanks for starting this thread, it helped me find the answer super fast.
