What should I do if the Win7 system adjusts the sound bar without sound?

1. First, let's open the sounds of your own voice and see if there is a disk-like icon. If there is, it means that the driver and computer installed do not match.

2, if the above situation occurs, then there is one sound driver in the computer, we find a click to open the sound speaker, click to open the sound control option inside the selection.

3, after opening, we need to select the sound driver suitable for our computer, check it and click OK.

4, if there is only one sound driver, then we can download the third-party software driver master to repair the software, click to open the driver master.

5, after scanning, and then click the sound driver to repair, close the window after the repair is completed and then restart the computer, and then see if the sound is already there.
