Abstract
An electronic device may exchange packets with a second electronic device. These packets may include transmit times, based on a given clock in a given electronic device when the packets were transmitted. Moreover, when the packets are received by the electronic device, the electronic device may store associated receive times based on a clock in the electronic device. Using minimum time differences between the transmit and receive times, the electronic device may calculate a time offset between the electronic device and the second electronic device, which may then be used to determine future times in a clock domain of the second electronic device. Moreover, the electronic device may provide additional packets to the second electronic device, where a given additional packet includes audio data, and a playback time, corresponding to a given future time, when the audio data is to be played back by the second electronic device.
