Turning up volume on DCC Sound Bachmann Class 37 loco

[Chrissaf]

Have Hornby Select Digital Controller.  Tried to increase volume on the loco however doesn't seem to have worked.  Followed advice on the Hornby DCC forum with CV176, 178 and 180.  Loco acknowledges input but sound doesn't increase or decrease.  What am I doing wrong please?

I assume that your Select has firmware release version 1.6 or 2.0 - please confirm if this is so.

.

You cannot adjust the appropriate CVs using a Select with firmware version 1.5 or below.

.

You say the Loco is a Bachmann Class 37 Sound loco. I have two of these and I do not recognise your quoted 176, 178 and 180 CVs. These look more like volume CV's used on Hornby TTS sound decoders.

.

My Bachmann Class 37 Sound locos have Loksound V4 decoders in them and my Master Volume is CV63.

.

Extracts from my Loksound V4 manual.

Looking at the full list of supported CVs in the Loksound V4 manual [extract below]. The CV list jumps from CV 134 to CV 246 therefore your quoted 176, 178 & 180 CVs are not CVs that are even supported in the Loksound V4.

Note that the Select even if upgraded to firmware version 1.6 or 2.0 is only able to write to CVs up to CV 255.

 Funny a lot of people thought it was too loud in the first place. Sound in a confined space can drive you crazy
