Frequently Asked Questions
What is HDMI ARC?
ARC (Audio Return Channel) sends audio FROM the TV TO a soundbar through a single HDMI cable. Only the HDMI port labelled ARC supports this feature.
Why do some apps have no sound but others do?
Some apps output audio in formats (Dolby Atmos, DTS) that your TV speakers or soundbar may not support. Change the app's audio setting to Stereo/PCM.
