Why is there no sound when my computer is turned on?

Please reinstall the system and come back to give me points.

It's hard to say why this kind of problem is.

The ghost system doesn't take much of your time.

No, no, you want to restore the settings that can be found in the default settings of the sound options in the control panel.

It's possible that the original sound was deleted by mistake! Find a disc system to fix it.

Did you optimize it?

The first reason may be the hardware, first plug in the headphones to see if there is any sound, be sure to plug in the right, if there is no sound, it may be that the computer audio output interface is damaged, it is best to find a professional to repair. Step to read.

If there is no sound on the computer and there is a small speaker, it may be that the small speaker is muted, check it, right-click to select the volume control, and remove the checkmark on all mutes.

If the computer has no sound and no speakers, restart the computer, repeat step 2 after restarting, if there is still no after repeating, click on the start menu, select the sound in the control panel - volume - device volume, and tick the volume icon. If you can't tick the box, there is no audio device on your computer.

If your computer doesn't have an audio device, you can click on your computer, select an empty space, then right-click to select Properties, select Hardware, and then select Device Management. If a yellow exclamation mark appears, it means that there is a problem with the sound card device and driver, and the corresponding driver installation of the computer sound card hardware can be solved.

If there is no sound in the microphone, right-click on the small speaker at the bottom of the computer, click on the volume control, select Properties, and tick in front of the microphone volume.

First of all, we right-click on "Computer" or "This Computer", select "Manage", click on "Device Manager", in Device Manager, we "Sound, ** and Game Controller", find the "Realtek High Definition Audio" device, we right-click on it and select "Disable Device", and then right-click and select "Enable Device". If there are multiple devices that don't know which is the sound card, disable all of them and then enable all of them, so that you can reboot.

This desktop speaker of yours can be used with other audio sources, but the reason why the computer can't use it is:

Due to the long use of the audio output socket of the computer, the reed inside has lost its elasticity, and the contact with the plug is poor, and the audio output socket of the same type needs to be replaced.

You can click the horn symbol in the lower right corner to see if the volume is off and set to mute? If the settings are fine, restart the computer to see if it is restored. If it doesn't work, there may be an audio pathway issue or a system software issue.

1.Check if there is a problem with the speaker.

2.My computer --- properties--- hardware--- device manager to see if there is no question mark. If there is, the driver is not installed, and you can install a universal sound card driver of the driver home.

3.If it's okay, it may be that Windows Audio (system audio service) is turned off, if you use 360, click first (optimize acceleration), then click (startup items), and then click (system key service items), find Windows Audio (system audio service) to see if it is turned on.

It's likely that your machine isn't plugged in, or the speaker isn't powered on, and if everything is fine, it's a software problem.

Software issues are either reset, redone, or sound-driven issues that need to be detected a little bit.

Log it out again to see if it's okay.,It should be affected by some program errors.。。。

The hole in the chassis is inserted incorrectly, and the hole is replaced by another one.

Reinstall your sound card driver.

It could be that your sound card driver is damaged.

You can use the driver life, or the driver wizard will automatically update your sound card driver after the use is completed.

What browser do you use?

Take a look at your browser settings.

Generally, third-party browsers have a small speaker in the lower right corner (I'm not talking about the taskbar small speaker).

Let's see if you've turned it off by mistake!
