Abstract

This application provides a display device and a method for controlling audio playback during multi-channel projection. The method records the terminal devices that establish projection connections with the display device based on a projection list, as well as the connection order between the terminal devices and the display device. When the display device establishes projection connections with at least two terminal devices, the audio modes of the multi-channel projection are adjusted through the projection list. One terminal device in the projection list is set to a non-mute mode, while the other terminal devices are set to mute mode, thus allowing the display device to play only the audio from one projection channel. This method allows for dynamic audio settings based on different projection scenarios and dynamic audio control based on user selection, resolving audio conflicts during multi-channel projection.
