EZCommand controls headlight ,also will dim light,forward and reverse work but no sounds . Loco has 28 speed decoder .
You don't mention the decoder manufacturer and model, not all DCC is sound capable. Are you sure you have a decoder equipped with sound? If so, the sound may be set to "mute", check your decoders instruction manual to see if it has a "mute" CV, and how to turn it off & on. Also be sure the loco has a working speaker and it's connections are good.
