Abstract
Described are techniques for configuring a selected audio device of a group of audio devices to send audio data to multiple other devices to enable the devices to provide a synchronized audio output. Link quality values indicative of the quality of communication links between audio devices and an access point and between different audio devices may be used to form subsets of devices in which a first master device receives audio data from a data source, provides data to other master devices via the access point. A value indicative of the airtime that would be used to communicate data to other audio devices may be determined for at least a portion of the audio devices. Additional subsets of audio devices may be formed if the airtime for the existing subset does not exceed a maximum quantity of airtime.
