Just recieved my new Silverado set, reviewed the video and paper instructions, assembled with no problems, new batteries in the tender and passenger cars, smoke switch "off", sounds switch "on" and cable connected to locomotive from tender.  Tender sound switch "on".
Runs and looks great, but no "sound".  RATS! 

Double/triple checked everything, no fix.

Help!  I would love to have the sounds working!

Thanks guys (and gals)!
