Frequently Asked Questions

Samsung soundbar HDMI ARC keeps disconnecting?

Intermittent ARC drops are usually caused by cable quality. Try a certified Premium High Speed HDMI cable. Also check for Samsung TV firmware updates in Settings > Support > Software Update.

Can I use a regular HDMI port for the soundbar?

No. Regular HDMI ports only carry video to the TV. Audio return requires the ARC-labelled port (or eARC on newer TVs) for the signal to travel back to the soundbar.

Anynet+ is on but soundbar still not detected via ARC?

Try a different HDMI cable first. If that fails, reset the soundbar to factory defaults (hold Off for 5 seconds), then reconnect and re-test the ARC link.
