The small speaker in the lower right corner of the computer is gone, and the computer is no longer s

It can be solved by the following three methods.

First: "Control Panel" - Sound and Audio Devices" - Put the volume icon into the taskbar "used to be manually turned off." Just turn it on.

The second way: "Put the volume icon into the taskbar" is checked, and it is invalid. Missing, file path C: Windows system32, you can upload one on another machine, or find a system disc to find the file and copy it to system32, then rename.

Type 3: If you have used software to delete startup items and accidentally deleted the volume icon of startup. At this time, the "Put the volume icon into the taskbar" is checked, and the volume icon appears, but the volume icon does not recover after rebooting, and it must be set in the control panel again.

In this case, the network connection icon may also disappear).

In this case, it is enough to restore the deleted entries in the startup entries in the registry.

Start "-Run" Enter regedit, open the registry, open hkey local machine software, Microsoft Windows CurrentVersion, run and create a new string in its right window"systray"(right-click on run) and the key value (double-click on systray) is"c:\windows\system32\", if it is a win2000 system, it is"c:\winnt\system32\"That's it.

Good luck!

The sound card driver may have been deleted by mistake. Right-click on the desktop "My Computer" to open the properties dialog box, click the "Hardware" tab, and then click "Device Manager" to see if there is a yellow question mark in the box that comes out.

If you feel troublesome, just go directly to the sound card driver, and come out with a search.

The sound card just re-drives.

Reinstall the audio driver.

I encountered this problem because I got the phone to send data, but no matter what the reason, the sound card re-drive can solve it.

Probably a sound card driven thing.

You go to the Device Manager and look for the sound card sign.

Maybe the audio driver is broken, just reinstall the driver!!

The solution to the computer is silent: there are two solutions to repair the system and install the sound card driver with software (first look at the small speaker or in the control panel to see if the mute is set, check whether there is sound output through the headphones, if there is, it is caused by the failure of the speaker, and if there is a damage to the sound card driver, if it is, please install the sound card driver such as the driver wizard and the driver life).

1. Press F8 to press F8 to get the advanced option to appear in the release of the power, and select "The latest correct configuration" Enter to repair.

2. The simple way is to use the system's built-in system to restore to repair when you don't have this failure (or restore the system with restoration software).

3. If the fault persists, please reinstall the sound card driver (reinstall the system if it is not possible).

Use the system that comes with the system restore method:

The system comes with the system restore: "Start" "Programs" "Accessories" "System Tools" "System Restore", click "Restore my computer to an earlier time", press Next, you will see that the date page has a dark date, that is the restore point, after you select, click Next to restore (win7 restore the system, in the control panel then the device and security sub-option and then the backup and restore sub-option).

**After installation, open the driver wizard, it will automatically detect your computer's hardware information, after the detection is completed, click the "driver update" button, switch the interface, and then click "automatic installation", and then click the "start update" button in the lower right corner (**** to your hi).
