一體機電腦音箱沒有聲音？

遇到一體機電腦音箱沒有聲音的困擾嗎？別擔心，php小編新一為您帶來了解決這個問題的逐步指南。這篇文章將深入剖析造成這問題的潛在原因，並提供清晰易懂的解決方案。繼續閱讀，讓您的一體機電腦恢復應有的音效。

一、一體機電腦音箱沒有聲音？

先看下驅動是否已安裝

情況一：右鍵桌面「我的電腦」——屬性——硬體——設定管理器——聲音視訊和遊戲控制器——這個項目下面如果沒有AC97或High Definition Audio或其他長串的英文，或是有黃色的感嘆號、問號。

情況二：點擊桌面左下角開始——控制面板——聲音、語音和音頻設備——聲音和音頻設備——裡面的所有設定都是灰色的，即是不可以用的。

A、如果有情況二，那麼有可能是windows Audio服務停止或停用了。解除方法：

右鍵點擊我的電腦——點“管理”，會打開電腦管理，在左邊，點服務與應用程式——服務，這時在右邊，找到windwos Audio，右鍵單擊它——點屬性－在“啟動類型”裡選“自動”，並點選“啟動”。如果沒有windows AUdio服務或此服務正常啟動或啟動不了的話,請看下面;

B、如果存在以上兩種情況的任一種，就說明沒有裝聲卡驅動。你買電腦時，如果有光碟的話，插進去試試看有沒有聲音驅動程序，有的話直接運行安裝就OK了。沒有的話,去http://www.drivergenius.com這個地址下載個驅動精靈吧，下載完安裝後打開，點驅動更新——找到多媒體或聲音或有嘆號或問號的選項——下載——安裝吧；或點驅動管理——勾選「聲音、視訊和遊戲控制器」那項或有嘆號問號的項—— 開始更新。

2、再看下是不是設定問題：

A、是不是音量被調到最小了或被靜音了：

雙擊右下角任務欄上音量圖標，打開「主音量」對話框,看下裡面的「主音量」「波形」有沒有被靜音或調到最小了。

B、看下是不是高清音頻​​與現在的台式機箱前面板不相容導致；

如果右下角任務欄上有音頻管理器圖標（粉紅色）的話，可雙擊直接打開音頻管理器對話框,然後點音頻I/O——點小扳手（模擬旁邊的那個，不是數字旁邊的那個）——第一項（其內容是AC97支持或禁用前面板）打上勾——再點OK。

如果右下角任務列上沒有音訊管理器圖示的話點擊：

開始——設定（有些電腦沒有）——控制面板——聲音、語音和音訊設備——高清晰音訊配置——音訊I/ O——點小扳手——第一項打上勾——再點OK。

二、電腦音箱沒有聲音插入手機卻有聲音？

電腦頻幕右下角有小喇叭，才有聲音。如果沒有，就是音效卡驅動壞了，裝好驅動就好了。如果有小喇叭，就是音響沒有插好，插中間那個綠色耳機孔。

你可以插耳機聽，如果還沒有聲音，就是電腦插口壞了。

三、電腦音箱沒有聲音大小開關怎麼辦？

請跟著我左手右手一個慢動作進行操作（僅針對台式雞，筆電沒試過沒聲音）

電腦右下角

或者控制面板的Realtek高清晰音頻管理器

右上角點“選項」

選擇AC97前面板

這樣一般來說就解決啦

AC97面板：AC 97的音訊插孔沒有感測開關，不能偵測是否有插頭插入。

HD音訊前面板：HD前面板插孔是帶開關的，可以偵測是否有插頭插入。

然鵝，不排除你電腦或耳機有其他的奇難雜症，反正我是這樣解決了

四、電腦音箱沒有聲音，只有嗡嗡聲是什麼原因，怎麼解決？

電腦音箱沒有聲音,只有嗡嗡聲，可能的原因是比較的多的，這個得逐一排查了，對應的原因以及解決的辦法有：

1、如果輸入音箱的音頻信號沒有插好,就會導致這樣的情況發生，所以要看是不是沒有插好。

2、在輸入音頻連接上沒有問題，就有可能是音頻線本身的有問題,內部的電線斷裂等，可以換一根線看看。

3、如果可以排除前面的兩種情況就有可能是影響的功放出現了問題，只有找專人進行維修了。

4、看看電腦與音響的連接線是不是連接好了，要是連接不好，不通電，也是沒有辦法傳送訊號的。

5、音響的喇叭出現了問題，沒有辦法正常的出聲了，這個也要進行修理。

6、還有就是音響的電源是否接通好了，如果電源的接觸不良也是會導致電腦音箱沒有聲音。

5. The computer speaker is broken, why is there no sound from the computer?

See if you encounter the following situations. If so, solve them according to the following methods:

1. First, check if you have accidentally set the mute setting.

2. Audio connection There is a problem with the line

3. Check if you accidentally uninstalled the sound card driver. If so, reinstall it

The steps are as follows: Open "Device Manager"---"Sound Card Name"---Select " Update Driver"---Browse your computer to find the driver---Select from the computer's device driver list---Next---then select the corresponding driver to install---OK.

4. Check to see if the audio device service is disabled. If so, just enable it.

The steps are as follows: Control Panel---Performance and Maintenance---Administrative Tools---Services---Windows Audio---Set the startup type to "Automatic" and then start it and it should be fine.

6. Computer Why is there no sound when I turn on the Amoi speakers?

Hardware reasons

　1. Poor contact

　The internal circuit of the speaker has been aged due to long-term use. When the speaker is connected to the computer, there may be no sound due to poor contact.

Solution: First check whether the audio connection is normal. If there is still no sound after making sure it is intact, you can install the driver and see if it is not good after installing the driver. That means the audio is broken. ​

　2. The audio cable is not connected properly

If the audio cable is not plugged into the corresponding jack, the volume of the audio is set to the minimum position or the speaker is not powered, the computer will have no sound.

Solution: First turn on the audio switch and turn up the volume. If there is no sound, look at the back of the computer host. The audio output at the back usually has three ports, which are red, green and blue. The red one is the microphone. , green is the speaker, blue is the output, the speaker wires are also colored, just plug into the jack of the same color. After plugging it in, turn up the speaker volume and try to see if there is any sound.

　3. The audio volume is switched to mute or too low

Sometimes the volume is accidentally set to mute or the audio volume knob is adjusted to the minimum volume, and there will be no sound.

Solution: Click the speaker icon in the lower right corner of the system, first confirm whether the volume is turned on, and adjust the sound to an appropriate size. If the "Small Speaker" icon in the lower right corner is also missing, go to the "Control Panel", double-click the "Sound and Audio Devices" item, in the pop-up "Sound and Audio Device Properties" window, select the "Volume" page, and then Adjust the volume adjustment slider to the appropriate position, and check the box next to "Put the volume adjustment icon into the taskbar", confirm and exit.

　4. The computer sound card is damaged

　Generally, the lack of sound on the computer is mostly related to the software, but the damage to the sound card itself does not rule out.

Solution: If it is determined that the sound card hardware is damaged, you can buy an independent sound card and plug it in. ​

Software reasons - sound card driver abnormality

​ The sound card driver is disabled, the sound card driver is damaged, or an unsupported device driver is installed, which are the main reasons why the computer speaker has no sound.

Solution: Right-click the "My Computer" icon, select "Properties" - "Hardware" - "Device Manager", open "Sound, Video, and Game Controllers". If a yellow "?" appears in front of it, it means The sound card driver is not installed properly. In this case, just reinstalling the sound card driver can solve the problem.

7. There is no sound when the mac computer is connected to the Bluetooth speaker?

Check the volume

First check if your Mac is muted, press and hold the F12 shortcut key or slide the menu bar sound slider to adjust the volume. Also check whether headphones or other audio devices are connected to the Mac audio port.

Check Audio Settings

If you connect headphones or other devices, you must check the input/output audio device settings. Sometimes driver errors can occur due to incorrect settings.

Launch System Preferences, select Sound, go to the Output tab, and make sure you select the correct audio output device. In case you mistakenly connect to a Bluetooth device instead of playing through your Mac's speakers.

To better check the output device, we can use the audio MIDI setting tool (search directly with the system search tool).

You can set the audio channel, bit depth, format, and rate in the built-in output. Exit the app after making adjustments and try playing the audio again.

Reset core audio

If there is a problem with core audiod, it will also cause the system sound to stop working or be distorted. In this case, you can try restarting coreaudiod.

Open Activity Monitor, search for coreaudiod, select it and click Force Quit. Coreaudiod will automatically restart after exiting.

If it doesn't restart (which rarely happens), shut down and restart your Mac. If the Mac cannot be restarted, you can also use the launchctl command to start the daemon and reinitialize coreaudiod.

sudo launchctl start com.apple.audio.coreaudiod

Third-party audio application issues

Using third-party audio apps may cause the sound on your Mac to not work properly. Since there are so many audio applications for Mac, it's impossible to provide an exact solution for every application. But in general, you can consider the following methods:

New versions of MacOS have software incompatibility issues, especially MacOS Catalina. Application software must first be "notarized" by Apple's security system. At this time, you can update the MacOS system version to make the software and system compatible.

Every audio application stores a configuration file in the Audio MIDI Setup Utility. If you see an error such as "Error in Core Audio's sound driver," delete the configuration file and restart the application.

Reset NVRAM

NVRAM is a small amount of memory used by your Mac to store various types of settings including volume, display resolution, time zone, etc. Resetting NVRAM can help clear glitches on these and other properties.

Shut down the computer, then turn it on and immediately press and hold four keys at the same time: Option, Command, P, R. Release after about 20 seconds to reset the NVRAM.

Check the output devices and ports

If the system speakers are normal, but there is no sound when connecting external devices, you can first check whether the output device is damaged and whether the port is blocked by dust. You can try to replace the device or unplug and reconnect the device.

Sometimes when connecting external devices, the sound continues to come from the system speakers. First make sure your device is compatible and there is no damage, then open System Preferences > Sound > Sound Effects to make sure the correct sound output device is connected.

8. There is no sound after the computer is connected to the Bluetooth speaker?

1. First, make sure the computer's sound is turned on. Check the speaker symbol in the lower right corner to see if it has been turned down to the minimum volume and whether you have clicked on mute.

2. Check whether the volume of the web page you are browsing is turned on, or check whether the volume of the player software is turned on. This is something that many friends tend to overlook.

3. If the above situation is normal, then you might as well check the driver status of the laptop. Download a driver wizard and scan it on the spot to see if the sound card is damaged and whether there is a new driver. If so, you can try to upgrade it.

4. Open the control panel, click Properties-Hardware-Device Manager, and observe whether there is an exclamation mark. If there is, it means the driver is wrong. You can double-click to solve it. Of course, you can also use step 3 to solve it.

5. You can use the computer clinic in Tencent Computer Manager to find a sound in the hardware and software and repair it. 6. If the situation has been solved and the problem has not been solved, then the last trick is to reinstall the system. If there is no change, take it to a repair shop.

10. What should I do if there is no sound when the computer speakers are plugged in?

If the computer speaker suddenly loses sound, first check whether there is a problem with the headset or the speaker itself connected to the computer. Try putting the headset or speaker on another computer to see if it can be used normally, then you can rule out whether it is an external problem. Among the reasons, if the headset or speaker is broken, it is relatively simple to replace it with a new one.
