In the operating system before Windows Vista, When you adjust the system volume, it is "Global. For example, when you listen to a song, you can adjust the volume to a relatively small State. Then, when you watch a movie with a storm video, the system volume is played in this state.
If you are a Windows Vista user, you can set the playback volume for them separately, and they are irrelevant. It looks a little hard to understand by text. Let's look at two pictures. Figure 1 shows the volume control attribute in Windows XP, and Figure 2 shows the volume synthesizer in Windows Vista ".
Figure 1 volume control attribute in XP System
Figure 2 volume synthesizer in Vista
If there is no comparison, no difference is found. From figure 2, we can intuitively see that for each different playing software, the window Vista system controls their respective volume separately, and users can adjust the playback volume of each player separately.
TIPS:
Window Vista does not assign a separate volume control button only for playback software. For other software that calls the system volume control, the system also assigns a separate volume control button.
