Not sure of this is a DCC question or n scale question, so I'll start with n scale. I have an Atlas S-2 - sound equipped right from the factory. Has worked great - until this evening. I was running along and the locomotive stalled. This is not unusual by itself, this happened near a switch and a spot where this has happened before - not unusual. I gave the loco a light shove and it resumed power. The engine start up sequence began over and the loco continued to move (I had previously programmed it to be able to move before the start up sequence completes). Everything fine and then - bam, loco stops stone cold. No sound. No response to any control except I could turn the light off and on. Ugh. I did a factory reset to the decoder, programming a value of 8 into CV 8. In fact I did it a few times. I was finally able to get the locomotive to run again, but I have no sound at all. It responds to throttle control just fine, in fact I messed around with the BEMF a little and it runs even better now than before, except NO SOUND. Any ideas on what to do next?
