RCA Sound Bar

[Mommanewby1]

Recently purchased RCA Sound Bar, hooked to our old plasma TV and sound only comes out 2 of the 4 speakers. Could it be our old TV not compatible for all 4 speakers to produce sound?

Makes and model number of both the soundbar and TV would help.

If you connected via optical cable you can try changing the audio output type in the TV audio menu.
You could select a different surround mode in the RCA if it has any.
The RCA could be defective. That would be my first guess if the the speakers that don't work are not surround related.
