The so-called "bilingual parallel", in fact, is the playback of audio and video files, from the speakers in both Chinese and English (or Mandarin and Cantonese). In the Windows 98 era, because of the problem of the suppression of video files, users can not be mediated through the system or playback software itself. Even later Windows XP, the problem is still not well resolved. Now, the same problem can be solved well under Windows 7.
On the Windows 7 System desktop, right-click the sound icon and select Play device from the pop-up menu (Figure 1):
In the Sound dialog box that pops up, select the sound device you are currently using (the grayed out device indicates that it is not currently available), and then hit the properties button below (Figure 2):
Later, Windows 7 will pop up the corresponding Sound Device Properties dialog box (this is the headset property), switch to the Level tab, and then click the Balance button (Figure 3):
Next, the system will pop up the "Balance" dialog box, where the user can use the slider to mediate the "remix" problem in the AV file (Figure 4).
After the modification, in the process of closing each dialog box, you will need to click the "OK" or "apply" button to save the settings exit.
