My Hornby County of Flint blew its DCC chip so I sent it off to Hattons and I decided to go overboard and have them fit a Loksound 4 & speaker, and they installed Olivia's steam A4 sound file http://www.oliviastrains.com/trains/mt/olivias-trains-sound-function-sheets/olivias-steam-sound-functions/
I was not that happy with the way it had been set up and, to avoid having to post it back from Spain to UK again, am trying to adjust things myself. I have downloaded the Loksound 4 manual, a lot of which is impenetrable to me, along with the Olivia soundsheet.
The chuff and other sound volumes are out of balance, the chuff being far to quiet. I read elsewhere about changing CV 31 to 16 (was already) and CV32 to 1, which I did. The separate sounds start at CV 259 but Railmaster via Elink won't read beyond CV255 despite setting CV range to read from 1 to 400. It does not get beyond 255. Is that a limitation of Railmaster? Which would mean I cannot balance the various sounds.
Something else I've been trying to overcome by adjusting acceleration rate is the fact that it gives a very long burst of steam as the brake is released and sets off quite fast with the steam still gushing; any slow chuffing can't be heard. Once the steam stops, the chuffs are then too fast for the speed.
My 2 Hornby TTS locos are much more user-friendly and sounds and implementation are much better. Steam brake off, loco starts with chuffing at the correct rate. I think I have wasted quite a lot of money and, in future, will be waiting for the standalone TTS decoders etc to become available. I'd welcome suggestions, thanks.
