I have just installed a Hornby 21 pin TXS Bluetooth and DCC sound decoder to my new Hornby Thane of Fife. I have put it on my DCC layout and it runs well but no sound. I have a NCE Powercab to control the trains. How do I get the sound to work?... apologies if this question has already been answered . I have been scratching my head and trying everything I could think of this afternoon but no joy. Appreciate any ideas
