Facing TV Problems? Ask a TV Technician.
Hello, That model number for the Samsung is not valid- please check it again.
Also, offhand Samsung sets use HDMI "ARC" (audio return channel) or "Optical Digital" for the best possible sound output to external sources.
Not sure if you already have a soundbox, but if so- then postback with the make and model of that as well and I can provide more details.
Do you need further assistance with this?
If not, could you please click the 5 STAR RATING, at the top of the page for my efforts? It is my livelihood and you can follow up at any time if needed.
