An optical disk device includes a reproduction component, an output component and a control component. The reproduction component directs a laser beam at an optical disk that is loaded in the optical disk device with the optical disk storing a plurality of audio data streams in a plurality of different acoustic qualities. The reproduction component reproduces one of the audio data streams. The output component outputs the one of the audio data streams to an amplifier. The control component acquires from the amplifier first audio format information indicating audio formats to which the amplifier corresponds, and acquires from the reproduction component second audio format information indicating audio formats of the audio data streams stored in the optical disk. The control component determines the one of the audio data streams with an audio format that belongs to both the first audio format information and the second audio format information. |
