Maybe we are used to work learning or entertainment, the background open QQ or other chat software, are also accustomed to their familiar message. I remember that when Windows 7 was first released, many people wondered why the other audio and video playback software suddenly dropped when the chat software came to the news. In fact, this is also the humanity of Windows7.
If you are used to the news, or if the message is necessary for you, then you can click on the "Communication" tab under "Playback Device". When you are active, select "Don't do anything", so that the background chat software will not affect the beautiful songs or wonderful movies when you come to the information.
If you really don't want to be bothered by boring news, you can turn on "Volume Synthesizer", where Windows7 will have all current sound output The applications are all gathered here for targeted mute or volume adjustment. If you prefer to listen to songs, then set your browser and QQ to be silent, and concentrate on your music world.
This feature of Windows7 is very user-friendly. It can easily control other programs without affecting the sound output of other applications. Instead of simply and rudely muting the entire system. If you think this feature is very convenient, you can pin it to the taskbar, so you have a volume control panel, adjust the sound state of the system at any time, work and play.
