Thanks for all the suggestions, although I'm not sure about the one about going to DCC from DC. Anyway, apparently the gremlins moved on. Last night when I tried the offending loco everything was fine. I may have hit the mute by accident but thought I had checked that when I was having the problem.
Anyway, thanks again.

mainetrains Anyway, all of the sudden some of the sounds have stopped working...horns, bells...etc.
Another thought would be did the volume accidentally get turned way down. There are CVs that control the volume of each This happened to me once when I tried to run the sound unit on DC. Came back to DCC with zero volume. The new QSI one can hold down F8 to adjust the volume.
Dave, if you are going to stay DC, better power pack like a MRC 2400 would not be a bad idea. If you are going to a bigger DC tack and want to run constants then a MRC 9500 is the way to go, but is close to cost of a starter DCC set up, around $90.00 but is the best DC power supply I have had.
If you want to go DCC and want to keep it simple, Bachmann E-Z Command use on E-Bay would be around $50.00.

Sometime an electrical short can play dirty tricks on a decoder. I would try a factory reset first and go from there.

I have a couple of locos which seem to have gotten some gremlins in the decoders. And before you ask no I haven't dropped them on the floor. Anyway, all of the sudden some of the sounds have stopped working...horns, bells...etc. The decoders were only put in a couple of months ago by a reputable dealer. Any ideas?
Thanks,
