No Audio from External Output (Soundbar or Receiver)

Symptoms:

• No sound when using HDMI ARC, Optical, or headphone jack

• Sound plays only from the TV speakers

Steps to Resolve:

1. Check Connection Type

   • Ensure HDMI cable is connected to the HDMI (ARC) port on both the TV and soundbar.

   • For optical, ensure the cable is fully inserted and not kinked.

2. Select Correct Output

   • Roku TV: Settings → Audio → Audio Output → select HDMI (ARC) or Optical (TOSLINK)

   • Non-Roku: Menu → Sound → Speaker Settings → choose External (HDMI ARC / Optical)

3. Enable CEC/ARC

   • Roku: Settings → System → Control Other Devices → enable ARC (CEC)

   • Non-Roku: Menu → HDMI-CEC → turn ON

4. Restart Both Devices

   • Power off both TV and soundbar for 1 minute.

   • Power on the TV first, then the soundbar.

5. Try Another Cable or Port

   • Use a high-speed HDMI cable labeled “ARC/eARC compatible.”

   • Test with a different port if available.
