An audio apparatus for processing arbitrary USB sound data by connecting a USB cable to a personal computer, comprises a USB connector portion for detecting a connected/non-connected status of the USB cable which is connected to the personal computer and a display tube for displaying contents of a communication status based on the connected/non-connected status of the USB cable detected by this USB connector portion. By this configuration, a user can easily and simply confirm a connected/non-connected status of the USB cable, in the audio apparatus having a built-in USB appliance, that is connected to the personal computer from contents of a communication status displayed on the display tube of the audio apparatus.
