Abstract

A method performed by a first device that has an internal clock. The method transmits a signal to a second device to share a clock of the first device. The method presents an extended reality (XR) environment and plays back audio content on the first electronic device, wherein the XR environment is also presented and the audio content is played back on the second electronic device The method generates timebase information that includes a first timebase that that defines a relationship between the shared clock and internal clock and a second timebase that defines a relationship between the first timebase and a playback state of the audio content. The method transmits the timebase information to the second device that synchronizes the playback state of the audio content in the second device, with the playback state of the audio content in the first device.
