Solve the silent sound of QQ video watching movies under Vista

In the Windows XP era, what impressed me the most was that after using Super Jieba (or Kingsoft ShadowPay) to play movies, and then using other software to chat (or watch movies), these applications became "dumb" ”, can't make a sound. I did not expect this to happen under Windows Vista.

One day, after the author and my friend video chat on QQ, open KMPlayer ready to see "Spider-Man 3" when it was discovered that "Spider-Man" became a "deaf-mute" & rdquo; Any sound is emitted from the system. Check the speaker cable, etc. are not abnormal, is it KMPlayer exclusive audio channel? This inevitably reminds me of the super solution. However, after the inspection, no abnormalities were found.

After some toss, I finally figured out the reason for the incident, which was caused by improper setting of the audio properties of the system. The solution is as follows:

Right click on the volume icon in the system tray (lower right corner of the screen), select <;sound& rdquo;, in the pop-up dialog box, switch to the “play” option, then double-click “ & rdquo; icon (Figure 1).

Then, another dialog box will pop up, then switch to the & ldquo; Superior & rdquo; tab, then uncheck the & ldquo; the permit application exclusive equipment & rdquo; to (figure 2).
