Win7 System computer suddenly has no sound how to solve?

The specific methods are as follows:

1, check the external audio equipment. We can usually use the substitution method to detect if the audio device is working properly. Connect our audio devices to the normal use of the computer if a sound proves the device is working properly. If you can't find another computer at a time, we can also use a smartphone to complete the test.

2, we confirm that the audio device is not a problem, the volume regulation is normal, and the computer connected to the correct situation, the computer is still no sound, then you can determine the computer system or software failure or set the wrong. To solve this problem, we need to use a software-driven wizard, I believe that we are not unfamiliar;

3, Next we download and install the software, here is not to repeat. You can search for "Drive Wizard", and then download from the official website. Official website provides a standard version and universal network card version, we can choose according to their own needs;

4, download and installation is completed, open the software, we click on the top of the "system Assistant", and then click on the "computer does not sound" under the "immediate repair";

5, the use of this function can be basically a one-time solution-because of audio services, driver problems and system settings caused by the lack of sound problems. If it is a driver failure, the software will automatically download and update the driver;

6, waiting for the restoration of the completion of the long absence of the voice back again.
