Abstract
A network device transmits to at least one playback device, audio information and playback timing information, wherein the audio information is associated with a first timestamp and a second timestamp; wherein the first timestamp and the second timestamp identify a time to playback the audio information; and wherein the playback timing information comprises the first timestamp. After transmitting the audio information and playback timing information, the network device receives while playback of the audio information is paused via the network interface, a command to resume playback of the audio information; wherein the audio information is paused prior to a time indicated by the first timestamp and second timestamp to play back the audio information. The network device instructs the at least one playback device to update the first timestamp, and updates the second timestamp to facilitate playback the audio information in synchrony.
