1. An information processing apparatus, comprising:
a display; a speaker; a connector detachably connected to a cable capable of outputting a video signal and audio signal; a processor; and a memory coupled to the processor, the memory includes an operating system and an output control module that are executed by the processor, wherein
a display driver being a module of the operating system and configured to control outputting of the video signal with respect to the display and connector in response to video settings,a sound driver being a module of the operating system and configured to control outputting of the audio signal with respect to the speaker and connector in response to audio settings that are independently made from the video settings,a detecting module configured to detect that the cable is disconnected from the connector,a resume module configured to restore a state where suspend is performed andan output control module configured to set audio settings that cause the sound driver to (i) switch an output destination of the audio signal from the speaker to the connector when the operating system notifies the output control module that the display driver has switched a display destination of the video signal from the display to the connector, and (ii) switch the output destination of the audio signal from the connector to the speaker when the detecting module detects that the cable is disconnected from the connector in a state in which the audio signal is output only from the connector and (iii) switch the output destination of the audio signal from the connector to the speaker, when a state in which the audio signal is output only from the connector is restored and a state other than a state in which the video signal is output only from the connector is restored, by the resume module.
