1. A television receiver comprising: a coaxial terminal to perform digital voice output, to which an external device is connected; an output level detection circuit to detect an output level of the coaxial terminal; a microcomputer to determine whether the external device is connected to the coaxial terminal or not, based on a detection result of the output level detection circuit; a display to display a connection of the external device to the coaxial terminal when the microcomputer determines the connection of the external device; a setting unit to set muting of an output from the internal speaker; and a voice mute circuit to mute a voice output from the internal speaker, when the microcomputer determines that the external device is connected to the coaxial terminal, or when the setting unit sets the muting of an output from the internal speaker.
