Bachmann 4-8-2 Sound problems

[urr617]

I have been working with a friend's fleet of Steam engines and trying to get the DCC decoders behaving properly again.
Right now my issue is with 3 of the Bachmann Spectrum C&O J-2 4-8-2's.
At one time they all ran properly and made noise (at least those with sound)
A little while ago, after sitting for a few months, I had trouble getting the DCC system to recognize the decoders. Then when the system did see the decoder, the engines still wouldn't run.
After more futzing around, I got one to move. However, I still haven't gotten any sound. I yanked the factory decoder out and installed a new Tsunami Medium Steam Decoder. Still no sound. And yes, I did check the speaker.
Arrghhh.

The programming has all been done through Decoder Pro v3.2
To be honest, I'm not entirely sure what exactly I did to get this far.

Does anyone have any helpful suggestions on how to fix this?
(Please no opinions on quality, etc, - just real advice)

Thanks much,

CV8=8
Did you somehow set CV 128 to 0?
Try setting CV19 to 0.
What ohm speaker are you using? 8 ohm should be max, 8 ohm preferred, 16 ohm can be used.

Any luck? Good, bad, or otherwise?
