Method 1: Check the Sound Control icon
If the computer has no sound, check whether there is sound control icon in the taskbar at the bottom right of the desktop, as shown in the figure below:
As shown in the preceding figure, if the sound card is installed on a computer, the sound card is correct. Click the Sound Control icon with the left mouse button, and the sound volume adjustment switch control window appears, check whether the volume is adjusted to the lowest, whether the mute is selected, many of the previous help many new friends to deal with the computer without sound is either the lowest voice, or select the mute, as a result, the computer has no sound. This is a low-level mistake that new friends often make.
If the volume control icon cannot be found on the desktop of the computer, it may be a driver problem. If the driver problem is found below, you will know how to refuse it. If it is not displayed, you can display it as follows:
If there is no "speaker" on the right side of the taskbar, go to the "start --- set --" control panel -- sound and audio device "command to open the" sound and audio device properties "dialog box, as shown in the figure below:
As shown in the preceding figure, click "& radic;" and then click "OK" in the task bar on the right bottom of the desktop. Then, check whether the volume is adjusted and whether it is muted, after the day off, the computer usually has a sound.
You can also click the sound tab in the dialog box, click a program event (such as a program error) in the program event column, and select another sound type, then check whether the "preview" button on the right is black. If it is black, the sound card is normal. The fault may be caused by the system volume being too small, mute, or speaker failure.
Other reasons: if the "device manager" window does not have the sound card option and the sound card is integrated with the sound card, restart the computer and enter the BIOS program. Then, check whether the peripheral device options in the BIOS are set to "Disabled". If yes, change it to "Enable. If this option is set to "Enable", it may be that the motherboard sound card circuit is damaged. Just repair the sound card circuit. It can only be repaired.
Method 2: Check whether the hardware is faulty.
If your computer has no sound, check whether there is a problem with your speaker or in-ear monitoring. Check whether the speaker or in-ear monitoring cable is properly connected to your computer and whether the interface is correct.
In the past, I found that when a friend was using a speaker or in-ear monitoring system, there was no sound due to the connection between the audio cable and the computer. This was also a low-level error. How could he make a sound even if there was no signal to connect to the Speaker ?? Some of them were directly connected to the microphone interface on the computer, and they all thought it was funny. One of the interfaces on the computer was the audio interface, and the other was the microphone. You must watch the microphone on your own. There are icons on it, obviously, if the Cainiao doesn't understand anything, they can ask the people around them and see more instructions than anything else. If there is a sound on the computer and there is no sound now, check whether the ears or speakers are damaged. You can have a good try.
Note that generally, desktop computers have two pairs of audio interfaces distributed in front and back of the chassis. If the interface is useless, try the plug-in at the end. Some computer installers may forget to connect the plug-in signal line in front of the host to the motherboard. I have also encountered many such cases.
Method 3: Check whether the sound card driver of the computer is properly installed.
In the past, it was often the case that the computer was not audible after the computer system was reinstalled. Most of these cases were caused by the absence of sound card drives or incompatibility, the solution is to install the driver corresponding to the computer sound card. How can I find out if the computer sound card driver is not properly installed? We can enter my computer --- right-click --- select --- properties -- hardware -- Device Manager as shown in the figure below:
Click Device Manager to view the hardware driver information, as shown in the following figure.
As shown in the figure above, the sound card driver is properly installed. The problematic sound card driver is installed. The sound card device has a yellow exclamation point! As follows:
If there is an exclamation mark in the sound card driver, it means that the hardware driver in the current system does not meet the driver of the computer. The solution can be to change the system. Of course, it is not necessary to find the sound card model of the computer, baidu directly finds the driver to install. How can I view the sound card hardware model of my computer? There are many methods. Here we will introduce several simple methods:
Method A. Start -- run -- enter: dxdiag command -- OK. Then you can open the Direct X hardware diagnostic tool and select-sound to view the sound card model. As shown in the following figure:
Method B. Click the yellow exclamation point shown in the preceding figure, and click "reinstall driver". Select "install from list", select the download sound card path, and click "OK" to complete the installation. It is recommended that you use the following method to download a "driver Genie" software, which is very convenient to install directly in the software. There are many such software, such as 360 Butler and other software.
No sound is reported when the computer is turned on and off, no sound is reported on QQ, and no sound is reported on the web page.
1) the solution to online nosound is as follows:
Start/run/enter "regedit", open the registry, and locate [HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Drivers32]
Create a new string value "wavemapper" on the right, and set the value to "msacm32.drv" (If yes, you do not need to create a value. If no value is set, right-click the blank area on the right and select a new string named "wavemapper". Double-click the value and set its value to "msacm32.drv". Press "OK" to restart the computer ).
Still not working. Try Firefox or Opera. You don't need to use IE as the kernel. If there is a problem with IE, you can also restore the system or reinstall it.
Use the built-in system restoration method:
System restoration: "Start", "program", "attachment", "System Tool", and "system restoration ", click "restore my computer to an earlier time" and click "next". You will see a dark date on the date page, that is, restore origin, click next to restore (Win7 restores the system, and then the device and security sub-options in the control panel, and then back up and return the atomic options ).
2) sound problems on the switch host
1. Check the "optimize windows sound and audio configuration" option of the optimizer. This will cause no sound on/off the host. Remove this check box and try it (if you have this software ).
2. Try the following method:
Start/run/enter regedit, open the registry editor, find the [HKEY_CURRENT_USER \ Control Panel \ Sound] branch, and change the Beep key value from "No" to "yes.
3. Open the control panel/sound, language, and audio device/sound/select the "Windows default" setting in the drop-down list of the sound solution, and click apply.
4. If the fault persists, restore the system or reinstall it.
