如果您有一台装有Realtek声音芯片组或驱动程序的(Realtek)Windows 7机器，那么您可能会遇到一个问题，即在通过扬声器甚至耳机播放音频时随机听到噼啪声、爆裂声或静电声。
在做了一些研究后，我意识到这是一个非常棘手的问题，它可能是由从延迟到驱动程序到其他硬件等各种问题引起的。在这篇文章中，我将尝试去通过所有可能的解决方案来修复 Windows 7 机器上的音频静态问题。如果您找到适合您的其他解决方案，请发表评论并告诉我们。
方法 1 (Method 1) – BIOS、视频(Video)和声卡驱动程序(Sound Card Drivers)
当然，在这些情况下，首先要做的就是更新驱动程序。在音频噼啪声和爆音的情况下，您应该更新BIOS驱动程序、视频驱动程序和声卡驱动程序。由于许多这些组件以某种方式连接，因此最好更新尽可能多的硬件驱动程序，而不仅仅是声音驱动程序。
对于Realtek，请确保您访问他们的网站并直接从那里下载最新的驱动程序。不要访问戴尔网站或尝试从Windows中更新驱动程序。

方法 2 (Method 2) – Disable Digital Audio In/Line输入
如果您的计算机有线路输入端口或数字音频输入端口，您可能希望在不再使用它时禁用它。如果您出于某种原因启用它，例如从电视或其他设备录制音频，那么如果您忘记禁用它，则可能会在播放音频时导致静电。
您可以通过右键单击任务栏中的音量图标，选择录制设备(Recording Devices )，然后禁用S/PDIF In 或任何其他Line In端口来禁用它。
方法 3 – DPC 延迟
根据您的系统，可能存在影响性能的高延迟，从而导致严重的音频问题。有一个很酷的程序叫做DPC Latency Checker，它可以实时监控您的计算机的性能。它将帮助您找出导致延迟的原因，例如网络适配器。
在下载页面上，他们还完整地解释了如何使用该程序来找出导致延迟的设备。基本上(Basically)，您希望看到像上面这样的绿色条，而在顶部的红色区域中什么也没有。如果您发现禁用网卡或其他设备会大大降低延迟，那么您可能必须使用制造商网站上的最新版本重新安装驱动程序。
方法 4 – 禁用 ATI HDMI 音频
这不适用于所有人，但如果您在Device Manager中有它，则可能是原因。你想去设备管理器(Device Manager)，然后展开声音、视频和游戏控制器(Sound, Video and Game Controllers)。在这里你想找到一个叫做ATI HDMI 音频(ATI HDMI Audio)的东西并禁用它。
方法 5 – 瑞昱和华硕
如果您有华硕(ASUS)机器和Realtek驱动程序，那么问题不在于驱动程序。这里需要卸载一些机器自带的音频软件，即Sonic Master和ASUS Asio。摆脱这些将解决噼啪声的问题。
方法 6 (Method 6) – 关闭实时程序(– Turn Off Real Time Programs)
如果您有任何实时软件，最好禁用它。这包括实时防病毒软件（甚至是Security Essentials）或实时CPU/hardware监控软件。应禁用任何其他类型的实时软件。然后检查静电是否消失。我也读过一些
方法 7(Method 7) –在 PC 上尝试不同的音频端口(– Try Different Audio Port)
听起来可能很奇怪，您可能会将扬声器或耳机插入计算机上的错误插孔。在许多机器上，您都有普通的耳机插孔，但您也可能有其他一些插孔，如HD Audio或其他东西。找到不同的端口并尝试将扬声器插入不同的端口，看看问题是否消失。它解决了很多人的问题。如果您的 PC 背面有数字音频插头，则尤其如此。在这种情况下尝试正常的模拟。
方法 8 (Method 8) – Disconnect Mouse/Keyboard
一些用户报告说，将鼠标和键盘与 PC 断开连接可以解决音频弹出问题。这可能是因为计算机上的某些端口仅适用于PS2鼠标和键盘，因此USB键盘或鼠标会导致问题。不知道具体细节，但试一试。如果断开连接后没有音频问题，请尝试使用不同的端口或使用不同的鼠标或键盘。
希望到目前为止，您已经找到了解决音频问题的方法！如果没有，请在此处发布您的规格和详细信息，我们会尽力提供帮助！享受！
Fix Audio Static Crackling Popping with Realtek Sound Card
If you have a Windows 7 machine with a Realtek sound chipsеt or drivers, then you may have run into a problem where you randomly hear crackling or popping or statіc while plаying audio through yoυr speakers or eνen headsets.
I realized after doing some research that this is a pretty tricky problem to fix and it can be caused by all kinds of issues from latency to drivers to other hardware, etc., etc. In this article, I’m going to try and go through all the possible solutions to fix the audio static on your Windows 7 machine. If you find a different solution that works for you, please post a comment and let us know.
Method 1 – BIOS, Video and Sound Card Drivers
Of course, the first thing to try and do in these situations is update the drivers. In the case of audio crackling and popping, you should update the BIOS drivers, video drivers and sound card drivers. Since a lot of these components are connected in some way or another, it’s a good idea to update as many hardware drivers as possible, not just the sound drivers.
For Realtek, make sure you go to their site and download the latest driver directly from there. Don’t go to Dell’s site or try to update the driver from within Windows.

Method 2 – Disable Digital Audio In/Line In
If your computer has a line in or digital audio in port, you may want to disable it if you are no longer using it. If you enabled it for some reason, such as for recording audio from a TV or some other device, then if you forgot to disable it, it could cause the static while playing audio.
You can disable it by right-clicking on the volume icon in the taskbar, choosing Recording Devices and then disabling the S/PDIF In or any other Line In port.
Method 3 – DPC Latency
Depending on your system, there could be a high latency affecting performance and thereby causing serious audio problems. There is a cool program called DPC Latency Checker that monitors your computer’s performance in real time. It will help you figure out what is causing the latency, such as a network adapter.
On the download page, they also have an entire explanation of how to use the program to figure out which device is causing the latency. Basically, you want to see green bars like above and nothing in the red area up top. If you find that disabling your network card or some other device drops the latency a lot, then you probably have to reinstall the drivers with the latest from the manufacturer’s website.
Method 4 – Disable ATI HDMI Audio
This won’t work for everybody, but if you have it in Device Manager, it is probably the cause. You want to go to Device Manager and then expand Sound, Video and Game Controllers. Here you want to find something called ATI HDMI Audio and disable that.
Method 5 – Realtek and ASUS
If you have an ASUS machine and a Realtek driver, then the issue is not the driver. Here you need to uninstall some audio software that comes on the machine, namely Sonic Master and ASUS Asio. Getting rid of these will fix the crackling problem.
Method 6 – Turn Off Real Time Programs
If you have any real-time software, it’s best to disable it. This includes real-time anti-virus software (even Security Essentials) or real-time CPU/hardware monitoring software. Any other type of real-time software should be disabled. Then check to see if the static is gone. I’ve also read that some
Method 7 – Try Different Audio Port on PC
As strange as it may sound, you could have your speakers or headphones plugged into the wrong jack on your computer. On lots of machines you have the normal headphone jack, but you may also have some other jacks like HD Audio or something else. Find the different ports and try plugging your speakers into the different ones and see if the issue goes away. It has solved the problem for a lot of people. This is especially true if you have a digital audio plug on the back of your PC. Try the normal analog in that case.
Method 8 – Disconnect Mouse/Keyboard
Some users have reported that disconnecting their mouse and keyboard from the PC fixed the audio popping problem. It could be because some ports on the computer are only for PS2 mice and keyboards, so a USB keyboard or mouse will cause problems. Not sure exactly of the details, but give it a shot. If you don’t have the audio problems once they are disconnected, then try using different ports or getting a different mouse or keyboard.
Hopefully, you have figured out something so far to fix your audio problem! If not, post your specs and details here and we’ll try to help! Enjoy!
