The current setup involves two devices connected to the TV, an IPTV box and an Apple TV, both of which have CEC enabled. The TV remote can effectively control the IPTV box, but fails to control the Apple TV. However, using the Apple TV remote will turn off the TV along with the Apple TV, making me wonder if anyone else has experienced similar compatibility issues with multiple devices enabled CEC. Despite unplugging the IPTV box, the issue persists, leading me to suspect that the incompatibility may not be a result of the device overload. I'd like to know if others have had similar experiences with CEC and whether they have found solutions to resolve the issue.
