What to do if the horn icon is missing in the taskbar

1, the first small horn is gone, we go to see if the computer still has sound output, if the sound has output, then it is good to do. Directly open your control panel, find "sound and video Device-volume" above, and then check the tick on the front of the "Put volume icon in taskbar" on the window. Then you can restart the computer. As shown in the figure:

2, if there is no sound output, it is more trouble. The aspects involved may also include hardware failure. First open the Add and Remove Programs-add remove Windows Components above Control Panel. Then put in the drive disk, in the "accessories and tools" Before the check mark, click "Next", the system will be prompted to install new hardware, and then install the prompts to install new hardware, after the installation is completed, restart the computer, See if the small horn and sound are normal.

But if the small horn icon is restored, the sound still has no output.

In this case, first of all foreign equipment to check, such as speakers, connectors, the interface is normal. Then check the sound card, sound card driver is installed. Detect "My Computer"----"Properties"---"Hardware"----"Device Manager", turn on the "sound, video and game controller" question, that is, to see if there is a yellow "?" in front. If so, uninstall it first, then put it in the CD drive and reinstall the driver for this device.

It is possible that the computer was in the virus, we try to use anti-virus software to kill the computer, or have an unexpected harvest oh.
