Abstract
A method is provided for an audio output device connected to a network to perform compatibility check. The audio output device discovers another audio output device connected to the network and transmits a first message to the other audio output device for checking whether the other audio output device is compatible with the audio output device. In response to the first message, the audio output device receives a second message from the other audio output device indicating whether the other audio output device is compatible with the audio output device. The audio output device, based on the second message, determines whether the other audio output device is compatible with the audio output device.
