Abstract
Methods, devices, and systems are provided for synchronizing a source device with a sink device. In some examples, the source device plays first audio using, e.g., an electro-acoustic transducer. The source device transmits a stream of packets to the sink device to be used by the sink device for playing second audio, where the playing of the second audio is to be synchronized within a predefined tolerance with the playing of the first audio. In response to determining there is a delay in average packet arrival times of the stream of packets at the sink device, the source device adjusts the playing of the first audio to maintain synchronization with the playing of the second audio within the predefined tolerance.
