Step-by-step fix
- Check HDMI Connections: Ensure the HDMI cable is firmly connected to the HDMI ARC/eARC port on your TV and the soundbar.
- Enable HDMI ARC/eARC: On your TV, go to the settings menu. Look for options like "Sound" or "Audio" and ensure HDMI ARC/eARC is enabled.
- Select the Soundbar as Output: In the TV settings, navigate to "Audio Output" or "Sound Output" and select your soundbar.
- Adjust Sound Settings: Check if there are any additional audio settings, such as "Pass-through" or "Bitstream," that may need to be enabled or adjusted.
- Restart Devices: Power off both the TV and soundbar. Unplug them from the wall for about 30 seconds, then plug them back in and power them on.
