As CSX Robert pointed out, part of the problem finding the information is your engine is a "Mainline" Walthers product, not a "Trainline".
To find the instructions for a Walthers product, you can just go to the Walthers website and do a search on the product you have. There are links in the product description to the instructions sheets, manuals etc.
So toward the bottom of this listing:
https://www.walthers.com/emd-sd70ace-esu-r-sound-dcc-norfolk-southern-1060-black-white
You'll find a link to the ESU CV list for that engine:

ndbprr Didn't your engine come with a list of the cvs and what they control?

Fergmiester I have a Walthers trainline SD70ace, which I find exceptionally loud. Does anyone know what the CV number and values are to bring the volume down several notches? thanks

Trainline or Mainline? I don't see any Tainline SD70's. There are links to various DCC information toward the bottom of the Walthers pages for those locos: https://www.walthers.com/emd-sd70ace-esu-r-sound-dcc-csx-transportation-4833-blue-yellow-white-roof-u-s-flag-lightning-bolt
You will have to identify the decoder installed by reading CV7, or checking the locomotives manual for the CVs used. The value in CV7 can be matched to a list on the NMRA website (or on the JMRI site) to identify the decoder's maker. Then the model/version will need to be identified by following the manufacturer's instructions.
If an ESU decoder installed, you'll need DecoderPro or a LokProgrammer to identify the specific decoder.
Outside of the mandatory CVs, the manufacturer can use whichever CVs they want for things like volume, so there is no default. OEM decoders don't necessarily support the same features that a retail decoder which you install yourself does, or use the same CVs.
The best place to start is the manual. Walthers probably has copies available for download on their website.
Need to know which decoder is installed. Is it an ESU?
