do not worry! Win7 sound is too big and small is not a fault

Many users are reflected in the forum, when the movie is playing on the Win7 computer, if the QQ comes a new message, the volume of the movie will become smaller. Similarly, when a video chat is performed, the volume of the music being played will also become very small. Unknown users think that there is a problem with the system, but it is not. This is a humanized design in Win7. Of course, if you don't think you don't need it, you can cancel it by modifying the system settings.

Click the Start button, type "sound" in the search box and press Enter to open the Win7 Sound Settings dialog.

Open Sound Settings

In the Sounds dialog box, switch to the Communications tab and set "When Windows detects communication activity" to "Do nothing".

Set to "Do nothing"

Click "OK" button to save the settings and close the dialog box. When you watch movies or listen to music later, QQ friends will not send messages. It will make the sound of movies or music smaller.

This feature of Win7 is actually to remind users, do not ignore the messages sent by friends. However, because everyone does not understand, so this function is not very used. In fact, there are many new features in the Win7 system, which can bring convenience and speed to our daily use. It is still beneficial to try to accept and get used to it.
