It may be that the exe virus is useless to redo the system Check it out for the next kill tool Note: The kill tool must not be run, check it again in safe mode Otherwise, the kill tool will also be infected.

There is no sound when the device is turned on.

Find the start, Settings, Control Panel, Sound & Audio Devices, Sound, and set the sound scheme to "Windows Default" to try ......

If it doesn't work, try it on the latest driver.

Let's see if there is a sound card driver? Didn't you accidentally delete it.

To set it up, in the "Control Panel" "Sound & Audio Devices", click the "Sound" tab, specify a sound file for the two items "Start Windows" and "Exit Windows" respectively, then drag the volume control bar at the bottom to the appropriate position, and click OK.

Also: When using the optimization function of "Windows Optimizer", I ticked the option of "Optimize Windows Sound and Audio Configuration", which caused no sound when switching on/off.

Second, the solution.

Method A: Use the recovery function of "Windows Optimizer" to "restore the attributes of the file system to the default values of Windows", and after restarting the system, the sound of power off and off will return to normal. Note: Do not check "Optimize Windows sound and audio configuration" during the next optimization.

Method B: Using the "Xuanxuan" method, it is easier to restore the power on and off sound by modifying the registry. Start running regedit, open the registry, find the hkey current user control panel sound branch, and change the key value of the subkey beep from "no" to "yes".

2 Control Panel - Sound & Audio Devices - Sound Tab - Sound Scheme - Select Windows Default.

Then it's okay to start over.

Update the sound card driver, and redo the system if it is not solved.
