If you have a Windows 7 machine with a Realtek sound chipset or drivers, you may have run into an issue where you randomly hear popping, popping, or interference when playing audio through speakers or even headsets.
After some research, I realized that this is a pretty tricky problem to solve and it can be caused by all sorts of problems, from latency to drivers, other hardware, etc., etc. In this article, I will try through all the possible solutions to fix static sound on your Windows 7 computer. If you find another solution that works for you, please leave a comment and let us know.
Method 1 – BIOS, video and sound card drivers
First method – BIOS, video and sound card drivers
Of course, the first thing to do in situations like this is to update your drivers. In case of crackling or cracking sound, you should update your BIOS drivers, video drivers, and sound card drivers. Since many of these components are related in one way or another, it is recommended that you update as many hardware drivers as possible, not just sound drivers.
For Realtek, make sure you visit their website and download the latest driver directly from there. Do not visit Dell website and try to update a driver from Windows.
Method 2 – Disable Digital Audio / Line In
Method 2 – Disable Digital Audio In / Line Input
If your computer has a line-in or digital audio input, you can disable it if you no longer use it. If you turn it on for any reason, such as to record sound from a TV or other device, if you forget to turn it off, it may cause static electricity when playing sound.
You can disable it by right-clicking the volume icon in the taskbar, selecting Recorders, and then disabling the S / PDIF input or any other line-in port.
Method 3 – Delay DPC
The third method – DPC latency
Depending on your system, high latency can occur, impacting performance and causing severe audio problems. There is a cool program called DPC Latency Checker that monitors your computer’s performance in real time. This will help you figure out what’s causing the latency, such as the network adapter.
On the download page, they also have a full explanation of how to use the program to figure out which device is causing the lag. Basically, you want to see the green stripes as shown above, and not see anything in the red area at the top. If you find that unplugging your network card or other device dramatically reduces the latency, you might have to reinstall the drivers with the latest version from the manufacturer’s website.
Method 4 – Muting ATI HDMI Sound
Fourth method – disable ATI HDMI Audio
It won’t work for everyone, but if you have it in Device Manager, this is probably the reason. You want to go to Device Manager and then expand Sound, Video and Game Controllers. This is where you want to look for something called ATI HDMI Audio and disable it.
Method 5 – Realtek and ASUS
Fifth method – Realtek and ASUS
If you have an ASUS machine and a Realtek driver, then the driver is not the problem. Here you need to uninstall some of the audio software that comes with the machine, namely Sonic Master and ASUS Asio. By getting rid of them, you will solve the problem with a bang.
Method 6. Disable real-time programs
Method 6 – Turn off Real-time programs
If you have any realtime software, it’s best to disable it. This includes real-time antivirus software (even Security Essentials) or real-time CPU / hardware monitoring software. Any other type of real-time software should be disabled. Then check if any static electricity has disappeared. I also read that some
Method 7. Try a different audio port on your PC
Method 7 – Try a different audio port on the computer
As odd as it sounds, you may have plugged your speakers or headphones into the wrong jack on your computer. On many machines, you have a regular headphone jack, but you may have other jacks like HD Audio or whatever. Find different ports and try connecting your speakers to others and see if the problem goes away. This solved the problem for a lot of people. This is especially true if you have a digital audio jack on the back of your computer. In this case, try the usual analogue.
Method 8 – Disable Mouse / Keyboard
Eighth method – unplug the mouse / keyboard
Some users reported that disconnecting their mouse and keyboard from their PC fixed the pop-up sound issue. This 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 about the details, but I’ll try. If after disabling them you have no sound problems, try using different ports or a different mouse or keyboard.
I hope you’ve already come up with something to fix the sound issue! If not, post your specs and details here and we’ll try to help! Enjoy!
