Solved! 45 “ Westinghouse TV. How to connect sound bar.?

Solution
Currently your AUDIO connection in order of preference are:

HDMI (digital, uncompressed surround highest fidelity)
Optical (digital, compressed surround)
Analog (stereo only, the lowest denominator)

So then you choose, just go from top to bottom, until u find what both pieces you are trying to connect have the same interface. Easy.
