Tried this in a few ways and can't seem to get mute/solo/record buttons to work in DAW mode with Cubase 12 (DAW mode set to Cubase). Tested with Cubase 10.5 and having same issue.
A Novation LaunchControlXL in HUI mode is able to control these fine in Cubase, so wondering whether this is a bug or something I've not setup correctly.
