Why is the sound of Lenovo computer noisy?

Have you ever encountered noise in the sound when using a Lenovo computer? Don't worry, you're not alone. Noise in the sound can be frustrating, especially if you are enjoying music or movies. Below, PHP editor Banana will introduce you to the potential causes of this problem and some troubleshooting tips to help you solve the problem of noisy sound on Lenovo computers.

1. Why is there noise in the sound of Lenovo computer?

The reasons why Lenovo computers have noise are as follows:

Satellite speakers are damaged: The reason why speakers produce noise is that a large part of the root cause of the problem is damage to the satellite speakers or sub-speakers. This fault may come from the box amplification circuit part, or it may be caused by the speaker itself. For example, if the volume is turned up too high while listening to music, causing the treble or bass part of the speaker unit to crack or be damaged, then there will be noise when you continue to use it.

File quality issues: Nowadays, online music is very popular. Many songs are downloaded from the Internet, which is convenient to use. However, precisely because of this open platform, the quality of the files also varies. For example, some music files are large in size when downloaded, but the quality is not very high, which will cause noise during playback. This is a problem that occurs during the file compression process and is almost impossible to solve.

Incorrect line input: Whether it is a 2.1 speaker or a 2.0 speaker, there is a connecting cable from the audio source to the speaker, which is the signal cable for the line input. If this signal line is not connected properly, it is likely to cause noise. For example, the general 3.5mm signal cable has a two-level plug. If it is not plugged in firmly, there will definitely be noise or even one channel being silent. Of course, if the line input is incorrect, it will also cause leakage from the chassis itself into the audio cable, and the noise will become more serious.

2. What should I do if the computer sound is noisy?

First, you need to determine whether the audio output device and audio cable are normal, and adjust the jack of the audio cable appropriately to avoid poor contact:

Second, right-click the desktop computer to enter the device manager, and try to update the driver to solve the problem:

Second 3. Right-click the taskbar sound icon to enter the "Sound" option, and set the sound scheme as the default scheme "Windows Default":

Fourth, right-click the taskbar High Definition Audio Manager and check whether the sound effect label is the default sound environment:

Extended information

A computer (also known as a computer) is an electronic computing machine used for high-speed calculations. It is called "one of the most advanced scientific and technological inventions of the 20th century."

Computers are composed of hardware systems and software systems, and have many functions such as numerical calculations, logical calculations, and storage memory. Its application fields have expanded from the initial military scientific research application to various fields of society, driving technological progress on a global scale.

The main structure of a personal computer (PC: personal computer):

Host: motherboard, CPU (central processing unit), main storage (memory), expansion card (display card, sound card, network card, etc. Some motherboards can integrate these), power supply Supplier, optical drive, secondary storage (hard disk), floppy drive.

Peripherals: monitor, keyboard, mouse (speakers, camera, external modem, etc.).

3. What’s wrong with the noise coming from the desktop computer?

This situation is because there is a problem with the speakers of your desktop computer, resulting in noise

4. The computer sound is loud. what to do?

01

Cause Stray electromagnetic wave interference is relatively common, and speaker wires, crossovers, wireless devices or computer hosts can all become sources of interference. Computer speakers are mostly active speakers, and there must be amplifiers inside them, so noise is inevitable. The noise from active speakers can be roughly divided into electromagnetic interference, mechanical noise and thermal noise according to the source.

02

Electromagnetic interference is generally caused by magnetic leakage from the power supply of multimedia speakers. When conditions permit, the effect of installing a shielding cover on the transformer is very obvious, which can block the magnetic leakage to the greatest extent. The shielding cover can only be used Made of iron material. Of course, we can also use an external transformer. If it is caused by interference from stray electromagnetic waves, move the main speakers as far away from the computer host as possible and reduce the use of surrounding wireless devices to reduce noise.

03

Microphone problem Sometimes there is noise because your microphone mix is ​​turned to the maximum. The solution is simple. First click on "Control Panel" - click on "Hardware and Sound" - click on "Realtek High Definition Audio Manager".

04

Click "Advanced Device Settings" - check the "Separate all input jacks into separate input devices" checkbox - OK.

05

If there is noise in the computer due to leakage of electricity from the motherboard, it may be that the motherboard of your computer is leaking electricity. Use a wire to expose the metal strips at both ends of the wire and connect one end to an uncritical metal part outside the computer host. Connect one end to the ground.

06

其他看電腦裡面是否安裝有不合適的程序，還有看電腦的主機配件是不是有鬆動。再內放的狀態檢查音箱，有問題就去維修店去維修一下音箱。

五、電腦聲音有雜音，呲呲啦啦的？

電腦有雜音可以按如下方法解決：　　1確保音響插頭已正確插入機箱後面板（一般電腦機箱後面板上粉紅色圓口是麥克風、麥克風插口；綠色圓口是音響、喇叭等擴音器插口；藍色圓口是線路輸入（如MP3）插口。　　2點選「開始」按鈕（也可以按下鍵盤上的windows徽標鍵）彈出開始功能表。滑鼠點選控制面板。看到控制面板頁面。　　3在彈出的「控制面板」頁面裡點選「硬體和聲音」（綠色字的）。以彈出硬體和聲音控制頁面。　　4在彈出的硬體和聲音控制頁面中點選「Realtek高清晰音訊管理器」（第6項，綠色字的）。以彈出Realtek高清晰音訊管理器頁面。　　5在Realtek高清晰音訊管理器頁面右上角有一個藍色字的「裝置進階設定」按鈕，點擊將會彈出進階設定頁面。　　6在進階設定頁面裡把「將所有輸入插孔分開為單獨的輸入裝置」前面那個單選框選取。然後按所有視窗的彈出順序倒序按「確定」。　　注意事項　　影響音響效果的原因通常有兩方面：1、線路問題。如接觸不牢靠，主機板漏電導致線路混進其他電壓和電流。最原始、最有效的解決方法就是加個電容吸收乾擾，但需要專業人士來做；2、就是電場和磁場的干擾。例如麥克風、手機、內燃機的電場，磁鐵、通訊基地台、衛星產生的磁場。最原始最有效的方法就是在音響外圍罩上一個完全密閉的鐵絲網，讓自成迴路的鐵絲網為音響形成一個靜電屏蔽罩。這樣可以屏蔽掉除音箱本身的所有電磁幹擾。

六、win10電腦聲音有雜音怎麼辦？

首先我們要查看是否安裝聲卡驅動，如果安裝了聲卡驅動也出現問題。那麼更新音效卡驅動，實在不行，前往聲卡官網下載最新驅動。

1、按下“Win+X”組合鍵，在彈出的選單中選擇“裝置管理員”； 　　

2、展開“聲音、視訊和遊戲控制器”，在下面的聲卡上點擊右鍵，選擇「更新驅動程式軟體」進行更新驅動；　　

3、或者我們可以下載「驅動精靈」、「驅動大師」等驅動管理軟體，進行驅動偵測；　　

4、如果發現有可更新的聲卡驅動，我們將其更新一下； 　　

5、檢查音響是否插入了在電腦的前置接口中，由於一般普通機箱前置面板的解除不是很好，會有接觸不良的現象，如果有請將設備插到後置接口即可。 　　以上也就是Win10電腦音響有雜音解決方法的內容了；
