Solution Description/Service Details:

reset CV125 to 1, changed F12 (volume toggle) to no sound, changed CVs 55,57,58,59,61 and 63 to zero. then changed CV5 (top V) to 23. This brings the sound to manageable and speed matches it back to 334B. I think what happens is that if there is a short on the layout, the controller sends a pulse down the layout that resets the CVs on the 334A unit. I have seen this phenomenon with another MRC controller and cheap decoders – of which this MRC is one.
