Abstract: This disclosure provides a display device and an audio playing method. The display device includes a processor, a first communication interface, and a second communication interface. The first communication interface is electrically connected to the processor and a player device. The second communication interface is electrically connected to the processor. In response to the processor receiving an audio detection command from the player device through the first communication interface, the processor determines whether a connection port of the second communication interface has a preset voltage. In response to the processor determining that the connection port of the second communication interface does not have the preset voltage, the processor responds to the audio detection command to occupy an audio system logical location. In response to the processor determining that the connection port of the second communication interface has the preset voltage, the processor ignores the audio detection command.
