電腦沒有聲音，怎麼辦？這個問題困擾著眾多用戶，讓工作和娛樂體驗大打折扣。 php小編小新為大家梳理了電腦主機沒有聲音的常見原因和解決方法。本文將從硬體檢查、驅動更新等方面入手，一步步引導您解決這個難題，讓您的電腦重新發出悅耳的聲響。
對於很多人來說，電腦主機沒有聲音可能是一個常見且困擾人的問題。沒有聲音意味著不能享受音訊內容，無法聆聽音樂、觀看影片或語音通話。在這篇文章中，我們將探討一些可能導致電腦主機沒有聲音的原因，並提供解決這些問題的方法。
一旦確定了電腦主機沒有聲音的原因，接下來可以嘗試一些解決方法。
確保您的音量設定正確，音量未被調低或靜音。
前往裝置管理員，尋找音訊驅動程式並更新或重新安裝它們。
確保揚聲器連接正確且沒有損壞。您也可以嘗試將耳機插入音訊插孔來檢查主機是否發出聲音。
檢查作業系統中的音訊設置，確保沒有靜音或其他錯誤設定。
在解決電腦主機沒有聲音的問題時，首先要確定問題的原因，然後嘗試對應的解決方法。如果您不確定如何處理，建議尋求專業協助以避免進一步損害您的電腦。
一、首先要確認硬體沒問題。如果喇叭沒毛病，音效卡也沒問題，如果你已經在其他的機器上測試過確實是完好的話，那麼可以繼續往下看。
二、確認所有的連接線完全正確。然後將音箱電源打開，音量開關打開。
三、正確安裝聲卡的驅動程序，如果是板載聲卡，就最好安裝主板驅動程序盤上提供的驅動程序（實際上，電腦不出聲，很多時候都是因為聲卡驅動不正確。一般情況下，音效卡驅動安裝好之後，在右下角的任務欄裡會有一個小喇叭的圖示。
四、如果肯定了驅動程式是正確安裝的，那麼再來看一下電腦裡的音量設定。
具體方法是：
雙擊任務欄裡的小喇叭的圖標，在彈出的“音量控制”對話框中查看“音量控制”和“波形”兩項裡是不是把音量關到最小，或者被設成靜音狀態。
如果以對話方塊中沒有這兩個選項，請點選「選項」選單－選擇「屬性」－在「顯示下列音量控制」中選取「音量控制」和「波形」兩項，再進行正確設定。
1、可能是電腦的音訊輸出裝置選擇錯誤，例如電腦之前連接過耳機、藍牙等其它設備。解決方法：嘗試將與電腦不相關的音訊連線裝置全部斷開，之後開啟音量並重新檢查。
2、可能是電腦的音效卡驅動出現了故障，導致電腦沒有聲音。解決方法：滑鼠右鍵點選「此電腦」圖標，之後依序開啟「屬性」、「裝置管理員」、「聲音、視訊和遊戲控制器」選項，最後嘗試將其中的驅動進行更新或重裝
1、插座接觸不良、訊號線接觸不良。
2、電腦設定問題，右下角喇叭設定成了靜音。
3、系統問題右下角沒有喇叭電腦出現沒有聲音的問題,如開啟電腦時無音,任務欄裡的小喇叭不見了:首先，電腦無音看似簡單，其實有時問題比較複雜，既涉及到硬體方面的問題又牽涉到軟體方面的問題。還有因突然死機導致音效卡不發聲、小喇叭消失的現像也較為常見。因此，要先查明原因，看是軟體故障還是硬體故障，然後針對問題對症下藥.
4、如果還是沒聲音，可以使用電腦管家——電腦診所——硬體問題——軟體硬體——聲音按照提示操作即可
First check if it is a hardware problem. Double check that the microphone plug is properly plugged into the computer jack. The microphone jacks on desktop computers are generally on the front of the case and on the back of the case, and are mostly red jacks. The microphone plug of the laptop is on the left side of the front of the laptop. Based on the correct installation of the hardware, check whether the computer driver is normal. Most of them are to check the audio driver of the sound card. This is relatively professional. Novice users can download software such as Driver Wizard for one-click driving to see if the audio driver is installed correctly. Third, if the hardware and driver are correct, QQ Microphone If there is still no sound, then you need to consider whether there is a problem with the system settings. In most cases, no sound from the microphone is caused by incorrect settings. In Win7 system: First, right-click on the speaker icon in the lower right corner of the taskbar, then select the recording device to check whether its settings are correct. You can right-click the microphone and select Set as default device
1. It may be that the headphones are not fully inserted into the computer audio interface. Re-insert them and confirm whether there is sound.
2. It may be that the headphone audio interface is wrong (plugged into the microphone interface). Change the interface and plug it in again to confirm.
Why there is no sound when the headphones are connected to the computer? The reason why there is no sound when the headphones are connected to the computer
3. It may be that the audio interface driver is not installed on the computer. Use the driver software to update the driver to solve the problem.
4. If the computer problem is eliminated, the headset itself may be faulty. Try replacing the headset and try again
I don’t know much about computers, so I don’t know how to solve it. I would like to ask a computer expert here, how to solve the problem of no sound from my tablet? Analysis and solution: Tablet computers are not as good as assembled computers. The lack of sound is usually related to settings. If there is a problem, you can read the manual carefully and check whether it is a setting problem on the tablet that is causing no sound. If it is not a setting problem, it may be a hardware problem. You can only go to the maintenance department. Generally, you cannot solve it by yourself. If you are strong in hands-on skills, you can try Just root. Nowadays, tablet computers are becoming popular very quickly. Some cheap, unbranded tablet computers are of very poor quality and are prone to problems. Problems such as no sound are even more common. Therefore, in order to avoid problems, it is recommended that users buy regular brands. For products, it is better to choose imported first-line tablet products.
You can try the following operation methods
1. First, let’s check whether the volume of the sound option in the lower right corner of the computer desktop is turned on. Click the icon with the left mouse button.
2. If there is no problem, open the browser. Check to see if the volume is turned off while playing the video, and turn the volume up.
3. If there is still no sound, there is a web page volume control in the lower right corner of each browser. Check to see if the sound is muted. If so, just click to open it.
4. If all these methods have been used and still don’t work, open the Sogou browser, enter: Flash in the search bar and click to download the software.
5. After downloading, open the installation package, select "Agree" in the license terms, and then click Install in the lower right corner to start installing the software.
6. After installation, close the browser and restart it. There will be sound when watching web videos and playing web games!
There is no sound. The main thing to check first is whether the connector of the external speaker is loose and whether the speaker is powered on? Check whether the sound card is normal. Have you turned off the sound of the web page?
1. Poor socket contact and poor signal line contact. Check that the speaker is powered on and that all signal lines are in good contact.
2. The most common fault of a power amplifier is a bad capacitor or a burned power amplifier tube. This is a problem for us, but most of it is due to the instability of the equipment itself.
3. Some power amplifiers will have a channel failure where there is no sound. The problem is still an internal circuit problem.
4. As for other faults, there are problems such as poor contact of the power amplifier volume potentiometer, unbalanced left and right channels, too frequent protection functions, poor contact of the work switch on the rear panel and the signal socket. In short, the power amplifier is the best in the current audio system. A kind of electrical equipment that is relatively prone to failure.
5. The most common fault in the speaker part is of course the speaker problem. It can be said that the most common fault in a sound system is a burnt-out speaker. Of course, this has human factors,
but most of it is the quality of the speaker itself.
6. Another common fault of speakers is that the wiring port is aging and has poor contact. This kind of failure is prone to occur especially in speakers that move frequently.
