If you’re on Windows 10 or Windows 7, and you’re hearing popping sound coming out from your speaker and/or your headphones, you’re not alone. We’ve received reports from many Windows users reporting it. But no worries, you can definitely get it fixed.
How do I fix it?
Here are 3 solutions you can try to get this problem fixed. You may not need to try them all. Just work from the top down until you find the one works for you.
- Set Minimum Processor State to 100%
- Disable ATI HDMI Audio
- DPC Latency
Note: The screens shown below are from Windows 10, but all the fixes apply to Windows 10 as well.
1. Set Minimum Processor State to 100%
Popping sound from your speakers or headphones could relate to your driver problem. To fix it: 1) On your keyboard, press the
Windows logo key

Control Panel from the list.
2) View by
Large icons and select
Power Options.
3)

4) C

6) Check to see if your audio crackling problem is gone.
2. Disable ATI HDMI Audio
In some cases, ATI HDMI Audio device in your Device Manager could be the culprit of the popping sound on your Windows PC. You can disable it for your audio to go back normal again. To do it: 1) On your keyboard, press the
Windows logo key and
X at the same time, then choose
Device Manager.
2) Click to expand
Sound, video and game controllers category. Right-click ATI HDMI Audio device driver if you can see it here and select
Disable device.
If you don’t see this option here, move on to next steps.
3. DPC Latency
In some cases, high latency could be the cause of your static audio among many other audio problems. Luckily, there’s a handy tool called
DPC Latency Checker. It helps monitor your PC performance and tells you what’s causing the latency. 1) Download
DPC Latency Checker and click the download file to open it. 2) If you’re seeing green bars as shown in the screen shot below, and nothing in the top red section, your PC is in a good state. Move on to the next step below.
3) If this screen shot is different from what you’re seeing, you’ll also see which device is causing the latency like this:
Try disable your device drivers from Device Manager as shown in
Step 2 one by one. If you find disabling certain drivers reduce the latency a lot, then you have to reinstall the device drivers to the latest version. You can update them all the needed device drivers one by one by yourself. If you don’t have the time, patience or computer skills to update your drivers manually, you can do it automatically with
Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee): 1)
Download and install Driver Easy. 2) Run Driver Easy and click the
Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click the
Update button next to any flagged driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click
Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the
Pro version – you’ll be prompted to upgrade when you click Update All).
