I have a new LM-4S-G module that I've downloaded the Heavy Steam and Steam Bell and a Whistle for a steam loco that it will be installed into. However, even though the sounds have been successfully downloaded, no sound comes out the speaker. Does the module have to have something else set up first like the motor full load current set first or something else? I never did this before on any other locos, I always installed the module then uploaded the sound, then did the full load current. I wanted to try something different this time to add some other things like sound amps before getting it into the loco.
