Illustratively, the first audio output device has a priority of 30, and the other audio devices connected to the controller have priorities of 10 and 20, respectively, so that the audio output device is set as the first audio output device.

Step S802: detecting whether a second audio output device is connected with the controller;

in some embodiments, the audio devices include, but are not limited to, headphones/bluetooth headsets, speakers/bluetooth speakers, ARC/eARC (audio return channel ) devices, WISA speakers, and speakers that are self-contained with the display device. The different audio devices are connected to the controller in different ways. For example: the Bluetooth sound box is connected with the controller in a communication way through Bluetooth. The ARC device is connected to the controller through a USB port.

The step of detecting whether a second audio output device is connected to the controller comprises: and detecting whether connection information of the second audio output device and the controller is received or not.

Illustratively, the bluetooth driver, upon detecting the access of the bluetooth speaker, sends connection information for the audio device to the controller, wherein the connection information includes the device type (speaker). The USB driver, upon detecting access to the ARC device, sends connection information for the audio device to the controller, wherein the connection information includes a device type (ARC).

If it is detected that a second audio output device is connected to the controller, step 803 is executed: acquiring the priority of the first audio output device and the priority of the second audio output device;

in some embodiments, the step of obtaining the priority of the first audio output device and the priority of the second audio output device comprises:

Determining a first device type of the first audio output device and a second device type of the second audio output device;

the priority corresponding to the first equipment type is determined to be the priority of the first audio output equipment, and the priority corresponding to the second equipment type is determined to be the priority of the second audio output equipment.

In some embodiments, a priority is predefined for the audio output devices supported by the display device, the priority being defined in advance by the product side. Such as shown in table 1 or table 2. This definition is the default priority of the individual output devices, which cannot be changed by the user throughout the system lifecycle.

if the priority level of the first audio output device is lower than the priority level of the second audio output device, determining that the priority of the first audio output device is lower than the priority of the second audio output device;

If the priority level of the first audio output device is higher than or equal to the priority level of the second audio output device, it is determined that the priority of the first audio output device is higher than or equal to the priority level of the second audio output device.

If the priority of the first audio output device is lower than the priority of the second audio output device, step S805 is executed: and switching the equipment for outputting the audio to the second audio output equipment.

In some embodiments, if the priority of the first audio output device is higher than or equal to the priority of the second audio output device, the audio output device is not switched to the second audio output device, i.e. the first audio output device is continued to be used for playing audio data.

In some embodiments, if the first audio output device has a lower priority than the second audio output device, the display is controlled to display an audio switch interface, the audio switch interface including a prompt, a switch device control, and a cancel switch device control. The prompt includes that the second audio output device is connected, is it switched to the second audio output device? And receiving an instruction of selecting a switching device control input by a user, and switching the audio output device to the second audio output device.

In some embodiments, at least two audio output devices may be set to the same priority, allowing the user to select themselves in the event that both of the same priority audio devices are connected to the display device.

If the priority of the first audio output device is higher than that of the second audio output device, the audio output device is not switched to the second audio output device, namely, the first audio output device is continuously used for playing the audio data.

If the priority of the first audio output device is equal to the priority of the second audio output device, controlling the display to display an audio switching interface, wherein the audio switching interface comprises a switching device control and a cancel switching device control;

When receiving the instruction of canceling the switching device control, which is input by the user, the device for outputting the audio is not switched to the second audio output device, namely the first audio output device is continuously used for playing the audio data.

Illustratively, if the priority of the first audio output device is equal to the priority of the second audio output device, an audio switch interface is displayed as shown in FIG. 10 that includes prompt 101, switch device control 102, and cancel switch device control 103. The prompt includes that the second audio output device is connected, is it switched to the second audio output device? The user selects the switch device control 102, and in response to a user instruction, switches the audio output device to a second audio output device. The user selects the cancel switch device control 103, and in response to a user instruction, the device for audio output does not need to be switched to the second audio output device.

In some embodiments, the corresponding priority of the audio output device may be defined by the user.

Receiving an instruction of setting the priority of audio output equipment by user input;

In some embodiments, the user may enter the setting interface by pressing a menu key of the control device 100, and display the audio output interface after selecting the audio output control in the setting interface. The audio output interface includes a priority setting control that is selected by a user to input instructions to set a priority of the audio output device.
