Abstract: PROBLEM TO BE SOLVED: To provide an audio device that can control the sound output depending on the operating state. SOLUTION: Estimated connection states to an external device and sound volumes in response to the connection states are stored in cross-reference with each other, when the audio device is actually in use, the estimated connection state and an actual connection state are compared, when the actual connection state is in matching the estimated connection state, the sound volume in response to the estimated connection state is extracted from the storage contents and used for a sound volume outputted from the audio device.
