Method 1: If you feel that this setting is not necessary, you can set the background chat software to not affect the sound of the system audio and video files when sending messages.

Click the "Sound" icon on the desktop taskbar of the Win7 system, and then select "Playback Device" in the pop-up menu. Then on the open playback device, switch to the "Communications" tab and select "Perform no action" when Windows detects communication activity.

Method 2: If the person says you don’t want to be attracted by boring news. You can directly open the sound icon on the Win7 taskbar and select "Open Volume Synthesizer".

The above are two methods for setting the sound do not disturb mode. Isn’t it very simple? I will never be disturbed by the sound again.
