Solve the parallel problem of watching movies in Windows 7

If you have been using a computer for 8 years, then you can definitely recall the following: when you watch movies with RealPlayer, Hero Super and other players under Windows 98, you often hear The Chinese and English (or Mandarin and Cantonese) "parallel" cases in the speakers.

The so-called "bilingual parallelism" is actually the simultaneous transmission of Chinese and English (or Mandarin and Cantonese) from the speaker when playing audio and video files. In the Windows 98 era, due to the problem of the suppression of video files, users cannot mediate through the system or the playback software itself. Even after Windows XP, this problem still not solved very well. Now, the same problem can be solved well under Windows 7.

On the Windows 7 system desktop, right click on the sound icon and select "Play Device" from the pop-up menu (Figure 1):

In the "Sounds" dialog box, select the sound device you are currently using (the device in gray status indicates that it is currently unavailable), then hit the "Properties" button below (Figure 2):
