Solve the phenomenon of popping and noise in Windows7 player

There are many users around the author who regard system settings as a system compatibility issue. When he watches HD movies under Windows XP, the player works normally, the picture is smooth, and the sound quality is very good, but when you go After the Windows 7 platform, the player often has popping and noise.

Windows 7 to play HD has pops and noise is compatibility problems?

For these problems, eliminate the problem once the player itself, many users blame the "Windows 7 and the Player" or "Windows 7 and the sound card driver" compatibility is not good. In fact, this is wrong, not a problem caused by compatibility, but the difference between Windows XP and Windows 7 in the multimedia service priority setting.

This situation is completely consistent with the method of playing high-quality MP3 files. Therefore, the author takes the existing data as an example and shares the solution with everyone.

done in my test files, in addition to the current "Subway Cry" and "McDull ringing", but I have used "Transformers 1", "Transformers 2," "Taxi 4" High-definition movies such as "Thirteen Arhats" have been tested. (This article was tested on October 19)
