Abstract:
1. A controller for enabling a plurality of audio files to be played on a computer subsystem of a computer system if said computer system is in an inactive state, said controller comprising: a switch having a first state and a second state, wherein said switch in said first state decouples said controller from said computer subsystem and from an audio integrated circuit (IC) coupled to said computer subsystem, wherein said audio IC is configured to play said plurality of audio file if said switch is in said first state, and wherein said switch in said second state couples said controller to said computer subsystem in response to said computer system being in said inactive state; a drive interface configured to interface with a drive of said computer subsystem depending on a state of said switch, wherein said drive interface is configured to access audio data on said drive if said switch is in said second state; and decoder circuitry for providing an audio signal to a speaker so as to play said plurality of audio files if said switch is in said second state, wherein said speaker is selectively coupled to said audio IC and said decoder circuitry according to said state of said switch.
