It is a TMCC engine and I just have TMCC controller. It lost sound and about 3 days later it came back! Then while pushing a few cars around yesterday day the sounds went out. It very well might have happened when over a switch as it was working in my industries.
I did try the AUX/0 to reset but nothing happened. I have tried Aux1 then 1 to raise the volume also with no success.
I might look into the "hard reset".
Thanks again guys.
