Ask the expert to solve the problem of computer audio connection!!

Double-click the volume icon in the lower right corner - Options - Properties - to see if the microphone is muted, the system is the default microphone mute, if there is no mute, look at the control panel - System - Hardware - Device Manager - see if the sound option has a yellow sign, if there is any, the driver is not installed, just reinstall it. If it's okay, look at whether the audio wire is connected to the wrong one,And whether the power of the speaker is turned on,Check whether the microphone is broken,If it's okay, you have to replace the sound card,It's good to integrate the sound card, just buy an external one30Pieces are there,Install the driver after installation。

You can't speak no matter what the microphone is plugged in

Where there is no sound, for example, you blow with a sound, and speak bel canto should.

It's funny for me .

I just loaded wheat for someone yesterday.

Go to the control panel to set it up.

Locate the sound and audio device.

Find the audio. There's a wheat thing in it that's forbidden.

Because the main board is different, the subject is different.

You look carefully and solve it absolutely

The most direct is to ask the computer maintenance personnel near you to give you the whole thing, because we can't see what the motherboard looks like, how the pins are arranged, and can't help you remotely.

I'm dizzy. of the 2nd floor. They are integrated sound cards. Can you plug it incorrectly??? If only I could. That must be a drive issue. Fixed.

It may be a problem with the chassis, the chassis is not good, and my front socket is not easy to use.

The front audio cable of the motherboard is connected incorrectly, open the case, and follow the steps in the motherboard manual to reconnect the audio cable.

It's okay if it's not plugged in, and it is recommended to swap it a few more times.

It may be that when you installed the network card, the sound card was moved, and it is recommended that you dial it down again, install it well, be careful, and then turn it on.

The integrated sound card can be turned off in the BIOS settings, did you turn off the sound card in the BIOS?

A factory reset of the BIOS should do the trick! Specifically, you can check the instruction manual of your motherboard!

There may be a conflict, unplug the network card, turn it on and see, or install a system with and without the network card.

Put down the optical drive of the motherboard, and then right-click on the device manager to install it.

This is not a driver problem, it is an audio glitch.

Suggestion: 1 Poor contact - test your audio jack with the light green of the host until the sound is normal (it does not have to be plugged in rigidly); Otherwise, the audio equipment is malfunctioning

2 If it is a new computer that you have just bought, find a merchant for after-sales warranty;

3 If it is a computer equipped by yourself, you need to find a merchant to replace the motherboard (the audio is on the motherboard) 4 Also, if you change the audio, there are also cases of audio failure;

5 If it is a speaker that comes with the notebook, you need to replace it with a new one.

Workaround:

1.Reinstall the sound driver.

2.Pay attention to whether the socket connecting the speaker to the computer is faulty.

3.Send the speaker to the manufacturer to check if there is any fault.

1. Check whether the sound card, cable, speaker and other devices are connected normally.2 Reinstall the driver of this device to solve the problem;

4. No sound and no speaker, open the control panel, add and remove programs, add and delete windows components, check the number before renting "Accessories and Tools", click "Next", and then, shut down and restart, the system prompts to install new hardware, and install according to the prompts;

5. Uninstall the sound card driver and reinstall or upgrade it.

6. When the first card driver of the sound cheat is installed, the prompt "AC chip cannot be found" appears, it may be that the computer is poisoned, or the sound card driver is deleted in violation of the operation, and the internal software conflicts. The solution is to reinstall the system and drivers.

7. After shutting down, wait for a period of time to restart the device"

See if you have the wrong holes!

There are a few things to note:

1. The power output of the computer is very small, and it must not be a speaker.

2. As long as the computer output is not short-circuited, there is nothing bad for the computer.

3. The so-called sound quality is related to many factors, such as the quality of your speaker, the size and quality of the listening space, the layout of the sound source, etc.

4. Looking at your problem, it seems to be to put some background for the company**. If the company's area is not very large, you can install a speaker with its own power amplifier that can be plugged into the U disk in the approximate middle position, and copy some ** in the U disk and let it put it by itself. If you want to put it through the computer, it is more troublesome to lay a sound source cable to the speaker.

If the company has a large area, it is still constructed to deal with it in the form of independent constant pressure amplifier and distributed speakers.

Figure 2 is obviously a passive speaker, and it must be power amplifier. **Buy a small volume of about 30w power amplifier, output from the computer to the power amplifier audio signal, amplify the output to the speaker.

Relatively speaking, I'm a person who pursues a**sound quality and listens to it on a computer**?? Hehe, after looking at your plan, you still have to use the power amplifier to spend some money, otherwise how to pursue it.
