Where a sound is greyed out / doesn't play then the sound file that the page links to doesn't exists on the server. There are quite a few of those.

If a sound is grayed out on the RP site is there a way to audition it before taking the time upload it to a hand controller?

No, if a playable sound is not on that page then there is no a way to hear it without loading it to a module.

Interesting. If they are grayed out, then I would think they should be removed.

I think this is what you're looking for. Scroll down on the page.

I have at least 10 G scale steam locomotives with the older version decoder. I recently bought two of the new LM-5S-G pre programmed
by the vender to light steam.
I am unable to find the set up screen for setting up the magnetic chuff sensors.
My HC is updated. When I look at one of my older decoders, the screen shows up.
What am I missing?

That was along the lines that I was thinking so I'll contact Ring and see what he says. Thanks LVRR for the response and I'll let you know what he says.
