There is no sound system on the computer at home, what microphone is used

The absence of sound has nothing to do with the microphone, the microphone can be plugged into the computer host, and the backplate of the host computer has red, black, and green (generally like this.) )

One of these three ports is plugged into a microphone.

You can use any microphone at will, and make sure that there is a microphone interface in the back, which should generally be a pink round hole!

Hello Kiss is happy to answer this question for you. Why is there no sound when the computer is plugged into the microphone?

First, plug in the wrong hole In general, as long as the computer sound card is driven correctly, after inserting the audio, you can hear the sound of a song, but some users do not know much about the jack of the computer sound card, thinking that you can use it normally by inserting a hole, although this idea is not wrong, but based on the different computer structure and system version, there may be a situation where the audio cannot be sounded. Sound card structure, it should be noted that do not plug the speaker into the front panel of the computer, although it can also be used, but you need to change the settings additionally, which is more troublesome for ordinary users, and you will kick it if you are not careful, you can directly insert the plug of the audio data cable into the sound card on the back panel of the computer (light green jack), you can hear the sound, if you plug it incorrectly, you can't hear the sound. Second, the connection error to the home audio as an example, generally by a subwoofer with two channels of small speakers used, in the connection of the output and input interface.

Under normal circumstances, one end of the data cable connected to the speaker will be plugged into the sound card on the back panel of the computer (light green jack), and the other end will be plugged into the "input" jack of the main body of the speaker, and then the subwoofer and the rest of the small speaker connection cables will be plugged into the "output" jack. Third, many users of audio switches often make some common sense mistakes, some speakers can not be used after connecting the power, there are one or more switches, the better the audio, the more switches it has. If you find that the computer speaker has no sound, the first thing to check is whether the switch of the speaker is turned on, whether the power supply is normal, many users because of the lack of understanding of the audio, often make some common sense mistakes, which is extremely common in reality.

Digression:In addition,There are some situations that will also cause the computer to plug in the speaker without sound,Such as sound card damage、Audio damage、Sound card drive error、The default output device of the computer system is set incorrectly, etc.,But this kind of problem is for computer novice users,Setting、Detection、It is difficult to maintain,It is best to find after-sales testing and maintenance directly。

If there is no wrong wire, you can be sure that the sound card software has blocked the microphone sound, and the solution is as follows:

1. First find the speaker icon in the lower right corner, place the cursor on it, and right-click to select the audio device.

2. Enter the sound settings interface, click the recording tab, tap the microphone icon, and set it as the default device.

3. Right-click and select the properties icon.

4. Enter the microphone properties interface, click the Level tab, and adjust the audio intensity of the microphone and microphone strengthening.

5. Return to the desktop, place the cursor on the speaker icon, right-click and click to select Sound Manager.

6. Enter the interface, click the microphone icon at the top, and turn up the volume below. At this point, the microphone will work normally.

The computer microphone speaks, and you can set it up to hear your own voice in the speaker.

Microphone settings: small speaker in the lower right corner Right-click Recording device: Set the existing microphone as the default device in the recording and then double-click the microphone or dot attribute In the level, you can adjust the volume of the microphone and the microphone enhancement (this is appropriately adjusted, turn it up, some computers will have current sound), and select noise suppression and echo cancellation in the enhancement.

Select Listen to this device in the listening,You can hear your voice in the speaker (don't choose this normal use,Some computers will freeze or make noise)。

In the audio manager, remove the x from all the sound channels and try to adjust the volume yourself, I just remember counting from left to right, the third or fourth from the bottom, but the volume should not be turned on too much, too much noise will occur.

The properties in the volume control settings --- front pink in and tick. Then unmute. Adjust the volume level. ok！

The microphone is muted, check all the places where the volume is controlled.

Is the microphone input cable connected?

Look at the taskbar (bottom right corner of the screen) and the volume icon (the little speaker). Launch - > Settings - > Control Panel - > sound and audio devices, select the "Volume" tab, tick the box in front of "Will be the volume icon in the taskbar", click the "OK" button in the taskbar "Little Speaker". Double-click the "Little Speaker" in the taskbar to open the "Volume Control" panel to see if there is a "Microphone" control panel, and if there is, jump directly to step 5.

The "Options" menu in the upper left corner - > Properties - > the volume adjustment bar "play" - shows the following volume control box, check the box in front of the microphone. Check the Mute box in the Microphone control panel of the volume control panel. Launch- >Control Panel- > Hardware & Sound- > Sound (Manage Audio Devices).

Select the "Play" tab, select "Speaker", and then click "Properties". Select the "Level" tab if the trumpet in the "Mic" column is disabled (there is a small red circle in the bottom right corner).

Summary. Why is there sound on a desktop computer without a microphone?

Hello, is there a murmur? Or a normal speaking voice.

If it is a noise, it is mostly caused by the speaker.

If it's a normal voice, it's likely to be a monitor or a built-in microphone in the desktop case.

Hope it helps!
