18. A system for wirelessly communicating audio content, comprising:
a first audio sink device;
a second audio sink device, wherein the first audio sink device and the second audio sink device are wirelessly connected via a hybrid link, and are each configured to render a different audio channel communicated wirelessly from an audio source device; and
a link manager residing on the first audio sink device, the link manager configured to:
select the second audio sink device to bidirectionally communicate with the audio source device, by:
enabling the first audio sink device to wirelessly receive a first audio channel from the audio source device via a first wireless link between the first audio sink device and the audio source device, and disabling the first audio sink device from wirelessly transmitting messages to the audio source device via the first wireless link, and
enabling the second audio sink device to wirelessly receive a second audio channel from the audio source device via a second wireless link between the second audio sink device and the audio source device, and enabling the second audio sink device to wirelessly transmit messages to the audio source device via the second wireless link;
compare a first quality associated with the first audio channel, with a second quality associated with the second audio channel; and
in response to the first quality being better than the second quality, select the first audio sink device to bidirectionally communicate with the audio source device, by:
enabling the first audio sink device to wirelessly receive the first audio channel from the audio source device via the first wireless link, and enabling the first audio sink device to wirelessly transmit messages to the audio source device via the first wireless link, and
enabling the second audio sink device to wirelessly receive the second audio channel from the audio source device via the second wireless link, and disabling the second audio sink device from wirelessly transmitting messages to the audio source device via the second wireless link.
