Step 2: Identify your audio output options Now unlatch the TV from the wall mount, place it face down on your prepared area, and take a look at what outputs it has available. If you don’t have blankets, find an area of clean carpet devoid of clutter. Grab a blanket and place it on a flat plane like a floor or a table that’s big enough. Of course, you may just have to take the screen off the wall. Pay close attention to the ports on the back of your soundbar or receiver.
