Win8 system prompts no solution for installing any audio output device

The Win8 system suddenly has no sound, and a red cross is placed on the sound icon on the right side of the taskbar, indicating that no audio output device is installed. Clearly plugged in headphones or audio, why Win8 will also prompt no audio equipment? There may be a problem with the sound card, so reload the sound card. If this method doesn't work, try the following method.

do the following:

1. From the desktop Win + R;

2. Enter & ldquo; regedit & rdquo; open registry editor;

3. Use the search to find, search “Audiosrv”, match with the whole word;

4. Delete the last two items of the data in the corresponding Data data after the RequiredPrivileges, only keep SeChangeNotifyPrivilege.

This method actually uses the registry to start the Audiosrv service. If the sound card driver is normal, the above problem will occur if the Audiosrv service is not started.
