1. An audio system comprising:
an audio source device comprising a first connector, the audio source device configured to provide audio information from a plurality of audio sources; a detachable audio device comprising a second connector for coupling to the first connector; and an audio/visual device for wirelessly connecting to the detachable audio device via a wireless link, wherein the detachable audio device is configured to cause the audio source device to select between causing audio corresponding to the audio information to be acoustically output through the audio/visual device and causing the audio to be acoustically output through the audio source device, wherein when the detachable audio device is coupled to the audio source device via the first and second connectors, a device discovery procedure is performed, wherein in response to the performance of the device discovery procedure, the detachable audio device transmits first device identity data to the audio source device through the first and second connector, and wherein the detachable audio device further comprises: an interface controller coupled to the second connector; a wireless transceiver; a first processing device; and a first storage storing a sequence of instructions that when executed by the first processing device causes the first processing device to:
operate the wireless transceiver to receive indications of a user operating a user input device to select between causing audio to be acoustically output through the audio/visual device and causing the audio to be acoustically output through the audio source device;in response to the user selecting causing audio to be acoustically output through the audio/visual device:
operate the interface controller to simulate coupling of a first audio controller to the audio source device through the first and second connectors at a time when the first and second connectors are coupled to trigger a first execution of a device discovery procedure through the first connector by a second processing device of the audio source device, andoperate the interface controller to respond to the first execution of the device discovery procedure through the first connector by the second processing device by providing the audio source device the first device identity data through the first and second connectors, wherein the first device identity data presents the detachable audio device as comprising the user input device and the first audio controller to enable acoustic output of audio by the audio source device through the detachable audio device to trigger an operating system executed by the second processing device to employ a first audio driver in acoustically outputting audio to cause the audio source device to employ the detachable audio device in acoustically outputting audio; andin response to the user selecting causing the audio to be acoustically output through the audio source device:
operate the interface controller to simulate uncoupling of the first audio controller from the audio source device through the first and second connectors at a time when the first and second connectors are coupled; and operate the interface controller by providing the audio source device, through the first and second connectors, second device identity data presenting the detachable audio device as not comprising the first audio controller to enable acoustic output of audio by the audio source device through a second audio controller accessible to the second processing device to trigger the operating system executed by the second processing device to employ an acoustic driver associated with the audio source device in acoustically outputting the audio. |
