Hi all, I have a TTS decoder. The decoder is working the train very well, and very smooth. But there is no sound when I press F1. So I decided to buy a new speaker, I connected it up, put back on track and still no sound. So I reset the decoder on CV8 and then reinstalled the loco back into the controller. Still nothing, I then reset CV8 but pressed 5 like the manual says to reset sounds...nothing! All connections seem ok...what is the issue??? Decoder works...two speakers and no sound lol....
