I've searched these boards and not found an answer to my question. Maybe I missed it somewhere, but will ask here.

I'm sure I read somewhere that there is a CV that silences the motor sound when the loco is stopped or has emergency stop applied. I am using Digitrax & toying with JMRI & a PR3 - mainly now for the withrottle - so neat.

I also saw a discussion of what CVs to alter in these locos. I didn't find the details tho.

BWT I know in real life the locos aren't shut down when stopped - but that is what I'm looking to do.

Thx in advance.

PS any N scalers in the area?

Perhaps you read or heard about CV 113 Quiet Mode.
Quote from: SoundTraxx

When the Quiet Mode is active, the decoder will remain quiet when it is first powered up and then automatically turn on the audio whenever it receives a non-zero speed command or any function is turned on (except Mute). It will automatically mute the audio when the locomotive speed is returned to zero, all functions are turned off and the time set in CV 113 has elapsed.

The Quiet Mode feature is not available in the SoundTraxx OEM Bachmann Sound Value decoder factory installed in the DD40AX.

Click Here for list of suported CVs.

Toggle F8 will turn all sounds Off and On.  Sounds come on when locomotive powered up even if muted by F8.

You will have to replace the decoder with one that supports what you want.

Well that answers why I could't find it. I understand F8, just wanted the sound not to start everytime I turn on track power, requiring an F8 each time.

Thx for the reply.
