Abstract
A detachable audio device structured to be coupled to an interface port of a computer system simulates the coupling and uncoupling of an audio controller to trigger an operating system being executed by a processing device of the computer system to select between an audio driver for that same audio controller and another audio driver for a different audio controller to which the processing device of the computer system has access, thus triggering a selection between causing audio played by the computer system to be acoustically output through either an acoustic driver to which the detachable audio device relays the audio or another acoustic driver associated with the other audio controller to which the processing device of the computer system has access.
