Hi all hope you can help
Started with my Sprog 3 this week, a second hand O Scale MP15dc works fine in terms of running backward and forwards and light on and off. I have tried returning to factory setting using JMRI Decoder pro and using the supplied wand with dc power. Still no sound,.... 
on DC or DCC has anyone any suggestions When i double press F6 the lights turn on so it clearly recocognises the command I have also tried double press F8 and F9?
Kind regards
Nick

Nick, did you ever resolve this problem? I'm not familiar with that decoder. I would ask is the speaker good? Is it connected?
Did it ever produce sound when using the SPROG? I had a similar problem with my Life Like P2k factory installed QSI decoders when I tried to run them with my SPROG 2, but when I took them to my LHS, they worked fine, sound and all. At that point, I stopped worrying about it, since I bought the SPROG mainly to do programming, and for that, it works way better than than my Digitrax PR3, which was replaced with a brand new one (still sealed in the package) by Digitrax.
