westinghouse and Nakamichi soundbar

[Debbie_42]

I have a Westinghouse WD43UB4530 hooked up to an xfinity cable box and just got a Nakamichi NK1B soundbar. The connector is a red/white from tv and has one port to soundbar. There is no sound. HELP. Thanks.

If you xfinity cable box has left and right audio outputs you can connect the soundbar directly to it.
If you have other sources or the box doesn't have those connections you need one of these

and cables connect it to convert the optical audio out of the TV to analog.
Check the TV manual on how to use the optical audio output.
Or return the Nak soundbar and get one with an optical input
