Quick checks

Before diving into a detailed troubleshooting process, perform these quick checks:

  1. Confirm that your HDMI cable supports ARC. A Certified Ultra High Speed HDMI cable is recommended for optimal performance.
  2. Make sure you are using the HDMI port on your TV that is labeled as ARC.
  3. Check that both devices are powered on and connected properly.
  4. Verify that the correct input is selected on your receiver.

Step-by-step fix

  1. Power Cycle Devices: Turn off both your TV and Onkyo receiver. Unplug them from the power source for about 30 seconds, then plug them back in and turn them on.

  2. Check HDMI Connections: Ensure that the HDMI cable is securely connected to the HDMI ARC port on both the TV and the receiver. If necessary, disconnect and reconnect the cable.

  3. Enable ARC on TV: Go to your TV settings. Look for the audio settings and ensure that HDMI ARC is enabled. This is often found under "Sound" or "Audio Output."

  4. Enable ARC on Receiver: Access the Onkyo receiver settings. Navigate to the HDMI settings and ensure that the ARC function is turned on.

  5. Update Firmware: Check for any firmware updates for both your TV and Onkyo receiver. Keeping your devices updated can resolve compatibility issues.

  6. Test Audio: Once you’ve made the above adjustments, test the audio by playing something on your TV. Adjust the volume using your TV remote to see if it controls the receiver.
