Facing TV Problems? Ask a TV Technician.
Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
Can you tell me how you have connected it and the model number of the soundbar?
The arc connection may not work (it often doesn't between different brands),
but what you'd have to do is go into the sony menu under the speaker/audio setting and set it to external/theater, and also make sure the bravia link (hdmi control) functions are turned on.
Be sure too that the hdmi port on the tv that you use is actually the one labeled as ARC, there is only one of them and it is usually the hdmi2 port on most tvs.
Thanks, ***** ***** know if you need help with pairing those other units.
