Frequently Asked Questions

Sony soundbar shows ARC connected but no sound?

The ARC link is established but the TV is still routing audio to its own speakers. Set Audio Output to HDMI ARC in TV sound settings.

Sony soundbar ARC drops connection every few minutes?

This is usually a cable quality issue. Try a new certified High Speed HDMI cable. Also update both TV and soundbar firmware, which often fixes ARC stability issues.

Non-Sony TV with Sony soundbar — ARC not working?

Enable HDMI-CEC on your TV (called Anynet+ on Samsung, SimpLink on LG). If CEC is unavailable, switch to Optical audio, which does not require CEC.
