Methods, systems, and apparatuses are described for testing communication with a device. A multimedia receiver may be communicatively coupled to a media device, such as a source media device. The multimedia receiver may transmit a test command to control the source media device using a communication protocol. A video frame output by the source media device may be obtained. Based at least on the video frame, it may be determined whether the source media device received the test command. In response to a determination that the source media device received the test command, an indication may be stored that the source media device may be controlled using the communication protocol.
