Win7 system web video playback no sound, how to solve?

1. First, we open the "start menu— run — enter regedit— open the registry editor"

2, then look in the registry below the path below, "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionDrivers32", go to the "Drivers32" path and see if there is a value called "wavemapper" in the list on the right.

3, if you do not find "wavemapper", that is largely the reason! We click on the right-click menu in the blank space, select "New & mdash; String value ".

4, then we rename the value to "wavemapper", double-click it, set the "value data" to "msacm32.drv", then restart the computer to see if it solves the problem .

Friendly Tip: If there is a "wavemapper" worthwhile, we may wish to click the volume control icon in the taskbar and select "Synthesizer".

Then look for the browser volume setting that you have used, and whether to mute the browser sound. For example, Xiaobian uses the Firefox browser, and the sound of the Firefox browser can be set separately in the "Synthesizer".
