win10 How to use the speaker speaker after connecting the external monitor? After the computer of the windows10 system is connected to the external display, if the display comes with a speaker speaker, how to make it play sound? Or the audio interface on the display allows it to be connected to the speakers for sound playback.

1, first find the speaker icon in the right corner of the status bar, then right click to select the playback device.

2. Select the speaker settings of the external display, right click and select “Set as the default communication device”.

Note:

HDMI cable or diplay cable with audio transmission should be used. VGA and DVI cables do not have audio function. Some have not sounded after the above method, because the default output sound of the display is zero, you should operate the adjustment button on the display to increase the sound. Not necessarily valid for every friend, but at least I know a solution, I hope to help everyone.
