Managing audio output through an intermediary
The present invention extends to methods, systems, and computer program products for managing audio output through an intermediary. In some embodiments, an audio controller emulates a direct connection between an audio source device and an audio output device. In other embodiments, audio content local to an audio controller is combined with other audio content passing through the audio controller on its way from an audio source device to an audio output device. In additional embodiments, an audio output device is locked to an audio controller. The lock survives power cycling and soft resets of the audio output device. A special hard reset can be used to release the audio output device.
