At least one non-transitory computer-readable medium, wherein the at least one non-transitory computer-readable medium is provisioned with program instructions that, when executed by at least one processor, cause a playback device comprising a first spectrum radio for communication via a first wireless spectrum and a second spectrum radio for communication via a second wireless spectrum to:

• operate in a first mode in which the first spectrum radio of the playback device is enabled and the second spectrum radio of the playback device is disabled;
• while operating in the first mode, receive a command to join a synchrony group with a display device and at least one additional playback device that is playing back audio content;
• based on the command, begin to operate in a second mode in which the second spectrum radio is enabled;
• receive the audio content for playback, wherein the audio content corresponds to video content being displayed at a display device;
• and
• using the second spectrum radio, coordinate with the synchrony group to take over, from the at least one additional playback device, playing back the audio content in synchrony with the video content.
