Step-by-step fix

1. Update Firmware: Go to the settings menu of your Sony receiver and check for any available firmware updates. Follow the prompts to install updates if necessary.
2. Check HDMI Connections: Ensure that all HDMI cables are securely connected. If any cables are damaged or outdated, replace them with compatible ones.
3. Audio Settings: Navigate to the audio settings on your receiver. Make sure that the audio output is set to Dolby Atmos or Auto.
4. Source Device Settings: On your source device, go to the audio settings and ensure that Dolby Atmos is enabled. This may be found under advanced audio settings.
5. Test with Different Content: Try playing different content known to support Dolby Atmos, such as specific movies or shows on streaming services, to see if the issue persists.
6. Reset Receiver: If none of the above steps work, consider resetting your receiver to factory settings. Refer to your user manual for the specific reset procedure.

If it still doesn't work
