1. A first playback device comprising: a network interface configured to receive audio data over a network; a plurality of speaker drivers; one or more amplifiers to power the plurality of speaker drivers; one or more processors; and tangible, non-transitory, computer readable memory comprising instructions encoded therein, wherein the instructions, when executed by the one or more processors, cause the first playback device to: (i) process the audio data before the first playback device outputs audio from the plurality of speaker drivers; (ii) determine that a type of pairing of the first playback device comprises one of at least a first type of pairing or a second type of pairing, wherein the first type of pairing comprises pairing with a second playback device and the second type of pairing comprises pairing with a plurality of playback devices; (iii) determine a portion of the audio data to be output by the first playback device based on the determined type of pairing of the first playback device and the audio data; (iv) when the determined type of pairing is the first type of pairing, determine a first time delay to facilitate sound synchronization with the second playback device; (v) when the determined type of pairing is the second type of pairing, determine a second time delay to facilitate sound synchronization with the plurality of playback devices; and (vi) configure, based on the determined type of pairing and the one of either the first determined time delay or the second determined time delay, the first playback device to output the determined portion of the audio data via the one or more amplifiers and the plurality of speaker drivers.
