What to do if there’s no audio coming from your center and/or surround speakers.
Here are some things you can check
- Verify that the S/PDIF cable (coaxial or optical) is firmly connected to the TV Box and the home theater receiver.
- Verify that the home theater receiver is set to a surround sound audio mode (Dolby Digital, Dolby Pro Logic II®, Dolby Pro Logic®).
- Verify that the receiver is properly configured to work with all connected speakers.

Note: This diagram shows HDMI connection only. Note that other cable types (coaxial, RCA, component) can be used to connect to the television.
