Can't help you on surround sound issues but my 2008 trailer has this
winegard wall plate (see photo below).
I have to switch my TV cable from the "amplified" output with
the lighted button to the Aux/sat connection when I'm hooked up to
cable at the camp ground.
Try that and see if you get your cable stations when you scan next time.
