Title: BLUETOOTH IDENTITY BINDING FOR VOLUME CONTROL
Abstract:
Techniques for controlling audio volume output by a paired device are described. A first notification indicative of a change to a first volume by a first audio output device is generated. The first notification comprises a first identifier of the first audio output device. A first record indicative of a volume of audio is stored. The first record is indexed by the first identifier. A second notification indicative of an audio stream being redirected from the first audio output device to a second audio output device is generated. The second notification comprises a second identifier of the second audio output device. A second record indicative of a second volume of audio output by the second device is retrieved. The second record is retrieved based on the second identifier. The second audio output device outputs audio at the second volume, based on the second record.
