Abstract: A device includes one or more processors configured to obtain output delay data based on a transmission from an audio output device. The output delay data indicates a playback delay associated with audio output by the audio output device. The one or more processors are further configured to determine, based on the output delay data and host delay data, a synchronization delay to coordinate audio output by the audio output device and video output at a display. The one or more processors are further configured to initiate sending of audio data to the audio output device and to send video data to the display. The video data is delayed, based on the synchronization delay, relative to the sending of the audio data.
