Fix Audio Static Crackling Popping with Realtek Sound Card

If you have a Windows 7 computer with a Realtek chipset or audio driver, you may have run into a problem where you feel randomly popping or popping or static while playing sound through speakers or even earphones.

I realized after doing some research that this is a rather difficult problem to solve and can be caused by all kinds of problems from latency to drivers to other hardware, etc. Etc. In this article, I'm going to try all possible solutions to fix static audio 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 driver, video and sound card

Of course, the first thing to try in these situations is to update the drivers. In the case of crackling and popping audio, you need to update the BIOS drivers, video drivers and sound card drivers. Because many of these components are connected in one way or another, it's a good idea to update as many hardware drivers as possible, not just the audio drivers.

For Realtek, make sure you go to their site and download the latest driver directly from l. Do not go to the Dell website or try updating the driver from Windows.


Method 2 – Disable digital audio input / input

If your computer has a line-in or digital audio port, you can disable it if you don't use it anymore. If you have enabled it for some reason, for example to record audio from a TV or some other device, if you have forgotten to disable it, it may cause static during audio playback.

You can disable it by right-clicking on the volume icon in the system tray, selecting Recording devices and deactivating S / PDIF In or any other port Line In .

Method 3: DPC Latency

Depending on the system, there may be a high latency that affects performance and, therefore, causes serious audio problems. There is an interesting program called DPC Latency Checker that monitors your computer's performance in real time. It will help you understand what causes latency, like a network card.

On the download page, they also have a complete explanation of how to use the program to figure out which device is causing latency. Basically, you want to see the green bars like above and nothing in the red area at the top. If you believe that disabling your network card or some other device greatly reduces latency, you will 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 everyone, but if you have it in Device Manager, it's probably the cause. You want to go to Device Manager and then expand Audio, video and game controllers . Here you want to find something called ATI HDMI Audio and disable it.

Method 5: Realtek and ASUS

If you have an ASUS machine and a Realtek driver, the problem 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 solve the crackling problem.

Method 6 – Disable the programs in real time

If you have software in real time, better disable it. This includes real-time antivirus software (including Security Essentials) or real-time CPU / hardware monitoring software. Any other type of real-time software should be disabled. So check if the static disappeared. I also read that some

Method 7 – Try different audio ports on PC

Strange as it may seem, you may have speakers or headphones connected to the wrong jack on your computer. On many machines you have the normal headphone jack, but you may also have other jacks like HD Audio or something else. Find the different ports and try connecting the speakers to the different ones and see if the problem disappears. It has solved the problem for many 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 the mouse and keyboard from the PC has solved the problem of the audio pop. It could be because some computer ports are only for PS2 mice and keyboards, so a USB keyboard or mouse could cause problems. I'm not sure exactly the details, but give it a shot. If you don't experience any audio problems after disconnecting them, try using different ports or getting a different mouse or keyboard.

I hope you have understood something so far to solve your audio problem! If not, post your specifications and details here and we will try to help you! To enjoy!
