Abstract
A method of managing an audio stream that is read by audio playback equipment in a manner that is synchronized on a reference clock is provided. The method includes the following steps implemented in said piece of audio playback equipment: receiving the audio stream, the audio stream being in the form of packets, each packet comprising a succession of audio samples associated with identification information characteristic of a timestamp of said packet; playing the audio samples contained in each packet and storing a time given by the reference clock that is characteristic of the moment at which a predetermined sample of at least one of the packets is played; and sending a message including correspondence information concerning the correspondence between the identification information characteristic of a timestamp of said packet and the time stored in the preceding step.
