Situation 2: Click on the lower left corner of the desktop to start all the settings in the Control Panel Sound & Audio Devices are grayed out, that is, they are not available. If either of the above two situations exists, you go straight to it.

**"Driver Wizard" software, after installing it, double-click to open Driver Update Tick "Sound** and Game Controller" Start Update Restart the computer after the update is complete. If the above two situations do not exist, please follow the steps below. Step 1:

If there is no small speaker in the lower right corner of the desktop, start the Control Panel Sound & Audio Devices tick on "Put the volume icon into the taskbar" OKZ

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. ）

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer.

The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly.

Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

1.Right-click on My Computer - Management - Device Manager.

Let's see if the driver is not installed properly.

If you have a yellow exclamation mark, you don't have it installed.

There is no sound problem on the computer, such as no sound when the computer is turned on, and the small speaker in the taskbar is missing, which often makes the rookies at a loss and don't know what to do. In practice, everyone will encounter similar problems. I've come across it three times on my computer.

After repeated exploration, I finally found several solutions. Now I dedicate it for the reference of netizens.

First of all, the computer is silent, but sometimes the problem is more complicated, involving both hardware and software problems. Therefore, it is necessary to find out the cause first, see if the software or hardware is malfunctioning, and then prescribe the right medicine for the problem. We must not mess around for unknown reasons, because if we don't do it, the system will be paralyzed, and the trouble will be big.

1. Check whether the sound card, cable, speaker and other equipment are connected normally; Run anti-virus software for anti-virus;

2. Right-click "My Computer" -- Properties -- Hardware -- Device Manager, and open "Sound, ** and Game Controller" to see if there is any yellow in front of you? "If so, reinstall the driver for this device to solve the problem;

4. When there is no sound and no speaker, open the control panel--- Add and remove programs--- add and delete Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system will prompt you to install new hardware, follow the prompts to install;

5. Uninstall the sound card driver, reinstall or upgrade the audio driver;

6. When the sound card driver is installed, the prompt "AC chip cannot be found" appears, it may be that the computer is poisoned, or the sound card driver has been deleted by mistake due to illegal operation, or it is a software conflict in the core department. The solution is to reinstall the system and drivers.

7. Simply ignore it, wait for a period of time after shutting down and then turn it back on, sometimes the sound problem will solve itself. You might as well give it a try.

Additions: Look at the sound icon and right-click to open the volume control to see if there is any muted or turned to the lowest.
