Mac: Disable just music, not in game sounds

Am keen to run Zwift with just game sounds, not the background theme tune, as that wears after a while and I’d rather listen to my own tunes.

The two Mac volume controls don’t cut it, can the music file be renamed perhaps?

Did see this, but that path doesn’t exist on my Mac, so looks like the install method has changed perhaps?

Open Finder. In the menu bar at the top, select Go > Go to Folder…

In the Go to Folder window, enter: ~/Library

Browse to the following folder: ~/Library/Application Support/Zwift/data/Audio/OSX

Rename the file 777200017.wem to something else (example: 777200017.wem.disabled).
