In some implementations, a computing device can calibrate media playback channels for presenting media content through a media system by determining the media propagation latency through the media system. For example, the computing device can send calibration content (e.g., audio data, video data, etc.) to various playback devices (e.g., playback channels) of the media system and record a timestamp indicating when the calibration content was sent. When the playback devices present the calibration content, a sensor device (e.g., remote control device, smartphone, etc.) can detect the presentation of the calibration content. The sensor device can send calibration data (e.g., media samples that may include the calibration content and/or a timestamp indicating when the media sample was detected by the sensor device) to the computing device. The computing device can determine the propagation latency (e.g., presentation delay) based on the calibration data received from the sensor device.
