Abstract: Embodiments included herein generally relate to measuring a latency of a playback device. For example, a method includes: determining a first latency of a playback device; determining a second latency of the playback device; comparing the second latency to the first latency to determine whether an event occurred at the playback device; and in response to detecting a latency change between the second latency and the first latency indicating the occurrence of the event, adjusting a timing of a data stream provided to the playback device based on the latency change.
