WinXP notebook How to troubleshoot a sound card does not support the MIX function

The sound card does not support the mixing function, turn on the small horn to adjust the volume, also did not find the adjustable "stereo mix" volume, where did it go? How can we rule out this failure?

The method is as follows:

1. Point "Start"-> "Run" enter "REGEDIT".

2. After the Registry Editor appears, locate the following path hkey_local_machinesystemcurrentcontrolsetcontrolclass{4d36e96c-e325-11ce-bfc1-08002be10318} 005SettingsfilterRear

You can also directly navigate to this folder by looking for "enableinputmonitor".

3. Create a new two binary value under the same folder: named "Digitalinputmonitor", "Digitalstereomix". Data with two key values is set to 1.

4. Close the Registry Editor, restart the computer, you can find in the "volume control" more than one item "input Monitor" this time our mic can be real-time playback, while the volume can be adjusted.

5. The recording control also has an option "stereo Mix", when the recording chooses to "Stereo mix" can realize the mixing function.
