Step-by-step fix
-
Identify the HDMI ARC port: Locate the HDMI ARC port on both your TV and the Denon AVR S540BT. It’s usually labeled as "ARC" or "HDMI ARC."
-
Use a certified HDMI cable: If you're unsure about the quality of your HDMI cable, consider using a Certified Ultra High Speed HDMI cable (paid link) to ensure optimal performance.
-
Enable CEC settings: On your TV, navigate to the settings menu and enable CEC (Consumer Electronics Control) options. This setting might be labeled differently depending on the brand (e.g., Anynet+, Simplink, etc.).
-
Adjust audio settings: Go to the audio settings on your TV and set the audio output to HDMI ARC. Make sure that any other audio output options are disabled to avoid conflicts.
-
Restart devices: Turn off both your TV and the Denon receiver. Unplug them from the power source for about 30 seconds, then plug them back in and turn them on.
-
Test the connection: Once both devices are powered on, test the audio output from the TV to the receiver. Play something that you know has audio to check if it works.
If it still doesn't work
If you have followed all the steps above and the ARC feature is still not functioning, consider the following:
- Check for any firmware updates for both the Denon receiver and your TV, as updates can resolve compatibility issues.
