不少笔记本电脑用户都因突如其来的“哑巴”遭遇了难题——笔记本电脑没有声音了。这到底是为什么？php小编苹果今天就为大家带来笔记本电脑没有声音的常见原因分析。
笔记本电脑没有声音的原因可能是出现了硬件故障。可能是因为扬声器损坏、音频接口故障或者声卡故障导致的。此时，需要检查扬声器是否正常工作，插拔耳机后是否有声音输出，或者通过设备管理器查看声卡是否正常。
有时候，笔记本电脑没有声音是由软件问题引起的。例如，声卡驱动程序损坏、音量被错误设置、系统静音等。可以通过重新安装声卡驱动程序、检查音量设置、关闭静音模式等方法来解决软件问题。
另外，笔记本电脑没有声音还可能是由于操作系统故障造成的。可能是操作系统发生了错误，导致音频功能无法正常使用。可以通过系统更新、重启电脑、检查操作系统音频设置等方式来解决操作系统故障。
检测和解决笔记本电脑没有声音的问题需要仔细分析，并根据具体情况采取相应的措施。无法自行解决时，建议及时联系专业人士或售后服务进行维修和咨询。
感谢阅读！希望本文能帮助您更好地解决笔记本电脑没有声音的问题。
我win10系统，刚才电脑听歌好好的突然没声音了，然后底下有个更新的图标，我就更新重启了还是不行，自己给捣鼓好了，首先打开计算机管理
然后点击左边的设备管理器
点开这个音频视频游戏控制，然后不要底下点那两个NVIDIA 的选项和英特尔的选项，右键剩下那个点击更新驱动设备
然后点击浏览我的电脑查找驱动就是底下这个
然后点让我从计算机可用驱动中选取，
这边就会出现当前的驱动和以往的驱动，随便选择一个以前的驱动然后点击下一页
然后等着它安装驱动，再试试播放音乐，基本上就会出现声音。这方法适用于正常使用中突然没了声音或者更新后没了声音。
如果还不管用，则右键小喇叭打开声音设置
然后点击右边这个声音控制面板
然后右键扬声器看有没有被禁用
这是我自己使用过的两种应对笔记本电脑没声音的方法，希望能帮到大家
注：本人只是个大学生，非专业电脑维修人员，只是凭借自己应对此类问题的个人经验，作答此问题，可能不适用于所有电脑没声音的情况比如声卡损坏等等
1、先检查一下电脑右下角的小喇叭图标，看音量是否调到了最小，或者静音了，如果有请调之。
2、问题如果没有解决的话，在桌上面，我的电脑右键->管理->设备管理器，找到声音、视频和游戏控制器，双击展示，如果一旦下面有一项中出现了“黄色的感叹号”，那么就是声卡驱动出问题了，解决的方法，安装声卡驱动(去官方下载，或者有备份过驱动的恢复驱动，再或者简单一点的，下载个驱动精灵，让它寻找有问题的驱动更新一下就解决了)
3、或者打开控制面板，找到声音和音频设备，双击打开，如果出现的情况，设备音量这一项都无法调节，音频中默认设备显示没有播放设备、没有录音设备，那么就按照上面的步骤来安装声卡驱动吧。
第二种情况：
1、如果你新买了个音箱或者耳机什么设备，又或者你因为搬电脑等原因，分开了音箱与电脑的连接，当再次连上的时候，出现了电脑没声音这种情况，那么解决的方法也很简单，只要你插孔没有插错的话，解决的方法是：开始菜单->设置->控制面板，找到Realtek高清晰音频配置，也有可能是其它的声卡，这里以用的最多的Realtek声卡为主，打开音频I/O，在右边的模板中，点开后面板中的耳机形状的图标，打开设备类型，在下面的几个选项中，选择符合你最佳的设备，例如有时候音箱没声音，选择音源输出即可，后喇叭输出也可，不过耳机就不行了，总之遇到这个问题一般就在这里，除非你的音箱坏了。
2、如果你把耳机插在前面板没有声音的话，按照上面第一步的操作，Realtek高清晰音频配置，在模拟那一项中，点击模板右边的“ 扳手 “形状的图标，打开接头设置，选择禁用前面板插孔检测，声音是不是回来了?
第三种情况：
说一下比较小白的网友经常遇到的：电脑右下角的音量调节图标(小喇叭)不见了，打开控制面板，声音和音频设备属性，把“将音量图标放入任务栏即可。

网上买了个usb声卡，今天刚到，刚接上用了十几分钟，忽然发现，拔下usb声卡之后还有声音！！！它又好了！！！我刚买的声卡啊。。。。。。。
所以还是老老实实等着吧，谁知道哪天就好了呢。。。。
2023.03.25更新
昨天笔记本休眠唤醒之后又没声音了，基本上每年一次，像犯病一样。。。。看运气了，说不定过几天就好了。。。
2022.02.22再更新
如果有一定动手能力的可以试试拆机，把有关音频的线都重新拔插一次，插紧。说不定就会好了。我前几天笔记本又没声音了，大概率是我换硅脂的时候有的线没插好。
建议仅供参考，没有把握拆机的还是不要动了，搞坏概不负责啊
以下是原回答
等着。
不是开玩笑，我就是这么干的。去年笔记本电脑就是这的问题。当时正常用着了，突然扬声器发出巨大的响声，然后莫名奇妙就没有声音了，而且耳机插上去也没声音了。但是音量能调，扬声器本身没问题。最奇怪的是，声音时有时无，看笔记本心情了。心情好就有，心情不好就没有。
然后去售后检测，售后让重装驱动和重装系统，但是还是没解决。售后又说可能声卡有问题，更换了声卡，问题依旧。
实在是没辙了，只能带回去，无声使用 。结果在过了大概两个月吧，突然好了？？？？到现在两年多了，再也没有问题。。。。。。
真就玄学。
笔记本电脑是我们日常工作和娱乐中不可或缺的设备,但有时候它可能会出现一些小问题,比如没有声音。这种情况下,我们该如何快速解决呢?作为一名专业的网站编辑,我总结了以下几种有效的方法,希望能帮助您轻松解决笔记本电脑没有声音的问题。
首先,我们需要检查一下电脑的音量设置。有时候,音量被调到最小或静音状态,这就会导致没有声音的情况出现。您可以通过点击任务栏上的扬声器图标来调整音量大小,或者使用键盘上的音量调节键来进行调整。如果还是没有声音,那就继续往下看。
如果音量设置没有问题,那可能是因为音频驱动程序出现了故障。您可以进入设备管理器,找到音频输入和输出设备这一项,查看驱动程序是否正常工作。如果驱动程序出现问题,您可以尝试更新或重新安装驱动程序。
除了检查音量和驱动程序,您还需要检查一下电脑的音频设置。进入控制面板,找到"声音"选项,检查一下默认的音频设备是否正确。如果不正确,您可以手动选择正确的设备。同时,也要检查一下音频设备的属性,确保没有被静音或音量被调到最小。
有时候,笔记本电脑没有声音的原因可能是硬件连接出现问题。比如,耳机或扬声器没有正确连接到电脑上。您可以尝试重新插拔一下连接线,确保连接牢固。如果还是没有声音,那可能是硬件本身出现了故障,这就需要您寻求专业维修服务了。
除了以上几种方法,您还可以尝试以下一些其他的解决办法:重启电脑,有时候重启就能解决一些小问题检查是否有其他程序占用了音频设备尝试使用不同的音频播放软件如果是新买的笔记本,可以联系厂商进行售后服务
通过以上几种方法,相信您一定能够轻松解决笔记本电脑没有声音的问题。如果还有其他问题,欢迎随时与我联系,我会竭尽全力为您提供专业的帮助。感谢您的阅读,祝您生活愉快!
第一步要检查笔记本电脑的音量设置。首先，确保音量没有被调至静音模式。其次，确认系统音量设置处于正常状态，可以通过点击系统右下角的音量图标来进行检查和调整。
Sometimes, no sound from your laptop may be caused by audio driver issues. You can check whether the audio driver is working properly by opening Device Manager and finding the Sound, Video, and Game Controllers option. If you find a problem with the driver, you can try updating or reinstalling the driver.
In addition, you also need to check the laptop’s hardware connection. Confirm that the headphones or external speakers are correctly connected to the computer's audio output interface. Sometimes, a loose connection can prevent sound from being output.
Some laptops are equipped with shortcut keys for silent mode, such as function key + F10. Check whether you accidentally pressed the mute shortcut key, causing the laptop to have no sound.
If the above steps do not solve the problem, you can try to run the system's own fault detection tools, such as the "troubleshooting" function of the Windows system, to diagnose possible audio problems.
If the problem still cannot be solved after the above steps, then the hardware may be faulty. It is recommended to contact the after-sales service center or professional maintenance personnel in time for further diagnosis and repair.
Hope the above methods can help you solve the problem of no sound on your laptop. Thank you for reading!
