A method of providing a synchronized secondary audio track via a mobile device. The method includes: receiving, at a mobile device, a request from a user to receive a secondary audio track that corresponds with a primary audio track of an audio-visual (AV) program which is presented to the user; receiving the secondary audio track at the mobile device; receiving at the mobile device a playback-control cue; and in response to receiving the playback-control cue, outputting audio data of the secondary audio track so that the audio data is synchronized with the primary audio track.
