Abstract
While operating in a first mode, a computing device transmits, to playback devices of a synchrony group, (i) media content and (ii) respective playback timing information for synchronous playback of the media content. After a first playback device with a different capability than at least one other playback device of the synchrony group has joined the synchrony group, the computing device begins to operate in a second mode for causing one or more of the playback devices of the synchrony group to modify playback of the media content based on a respective playback device capability. While operating in the second mode, the computing device (i) determines a modified sample rate for the first playback device to maintain synchrony of playback of the media content between the playback devices of the synchrony group, and (ii) causes the first playback device to play back the media content at the modified sample rate.
