Quick checks
Before diving into a detailed fix, perform these quick checks:
- Confirm that the HDMI cable is securely connected to the HDMI ARC ports on both the TV and the receiver.
- Ensure that your TV is set to the correct input for the receiver.
- Check for any firmware updates for both the TV and the receiver.
Step-by-step fix
-
Power Cycle Devices: Turn off both the TV and the Onkyo receiver. Unplug them from the wall for about 30 seconds, then plug them back in and turn them on.
-
Check HDMI Cable: Ensure you are using a certified high-speed HDMI cable that supports ARC. If unsure, consider replacing it with a Certified Ultra High Speed HDMI cable (paid link).
-
Connect to ARC Ports: Make sure the HDMI cable is connected to the HDMI ARC port on the TV and the HDMI OUT (ARC) port on the Onkyo receiver.
-
Enable ARC on TV: Go to your TV settings, find the HDMI settings, and ensure that ARC is enabled.
-
Enable ARC on Receiver: Access the Onkyo receiver settings, navigate to the HDMI settings, and ensure that HDMI Control (or similar) is enabled.
-
Test Audio: Switch the TV to a channel or app that you know has audio output, and check if the sound is coming through the receiver.
-
Adjust Audio Settings: If audio is still not working, check the audio output settings on the TV to ensure it is set to output sound via HDMI ARC.
If it still doesn't work
If you’ve followed the steps above and ARC is still not functioning, consider:
- Trying a different HDMI cable or port.
- Updating the firmware on both devices.
- Consulting the user manuals for specific troubleshooting tips.
