Abstract: A list screen of a plurality of reproduction devices is displayed on a display unit based on relationship information between the plurality of reproduction devices which is connected via network. Selection of a reproduction device which is made to perform a content reproduction operation among the plurality of reproduction devices is received. A command is transmitted to the selected reproduction device.

Abstract: In a case where a sound of one channel of an audio signal which is reproduced and emitted by a second audio device is emitted from a first audio device, an audio device receives a signal of other channel of the audio signal from the second audio device and causes a sound emission unit to emit a sound of the other channel.

Abstract: A connection confirmation system includes a connection detection apparatus and an information processing apparatus communicable with each other. The connection detection apparatus acquires a setting relating to a connection mode of a device to be connected to a sound processing apparatus, detects a connection mode of a device actually connected to the sound processing apparatus, and determines a difference between the detected actual connection mode and the connection mode indicated by the acquired setting.

Abstract: Provided is an audio device, including: at least one processor; and at least one memory device that stores a plurality of instructions, which when executed by the at least one processor, cause the at least one processor to: play, with a given length of delay, a first-channel audio signal included in an audio signal; obtain one of operation information about operation of the audio device and setting information about playing of the audio signal; and transmit one of the operation information and the setting information, and at least a second-channel audio signal included in the audio signal, to another audio device.
