I have been busy with other things since I installed win7, and I have no time to go to the video network. I have time to go online and watch a video tutorial. I don't have a sound after I open it, so I can watch music and video play. No problem. Alas, why is there no sound on all video webpages? It must be a system problem. find it on the Internet. The solution is as follows:

 

When using the Windows 7 test, many users found that they had no sound when playing Flash videos on websites such as YouTube, Tudou, Youku, and rmvb and WMV in online movies, the same is true for music on webpages. Playing the video, music, and Flash animation on the hard disk is normal and audible. So where can I solve this problem by setting Windows 7? This problem is also common in Windows XP and Windows 7 to disable special effect Vista. It has nothing to do with Windows 7. It is generally caused by the use of optimization software or the installation and uninstallation of various decoders. To solve this problem, click "start"> "run" and enter"Regedit" and press enter to open the Registry Editor. In the left-side pane, click "HKEY_LOCAL_MACHINE // software // Microsoft // Windows NT // CurrentVersion // drivers32 ", then, in the right pane, check whether there is a "wavemapper" value. If no, right-click the download white area of Windows 7 RC in the right pane and create a new string value "wavemapper, double-click the value and set "value data" to "msacm32.drv". restart the computer to solve the problem.Tip: If there is no sound after setting according to the above method, check whether there is a volume icon in the system tray. If not, open "audio and audio device properties" and select "place the volume icon in the taskbar" for the win7 x64 optimization master.
