Unfortunately I don’t own the WM1ZM2. I don’t have the gold volume control UI for my WM1AM2.
Did you disable anything outside of what I have listed?
I think your best course of action is to roll back what you have disabled. It should solve the issue.
I disabled everything on your list, golden volume knob is still on.
Way to go @kenjamin0523 , you just downgraded your WM1ZM2 to WM1AM2
