Abstract
A computing system is configured to: after receipt of a request to initiate synchronous playback of media content on a plurality of playback devices via a communication interface, obtain the media content from a media source; generate playback timing information; transmit the media content and the playback timing information to the plurality of playback devices for playback in synchrony; while the plurality of playback devices play back the media content in synchrony and after receipt of respective playback rate information from at least one of the plurality of playback devices indicative of a rate of playback of the at least one playback device, (i) determine a modified sample rate of the media content for the at least one playback device based on the respective playback rate information; and (ii) cause the at least one playback device to play back the media content at the modified sample rate to maintain synchrony.
