Dolby Audio Problem: Popping/Crackling Noise (Acer Predator Helios 300) [JULY 2018]

kekaju123

Hey there, I am facing an annoying problem here: just recently, my laptop is making popping/crackling sound when a music/sound is played.

I noticed that the problem happens when the program Dolby Audio is turned on. Googled tutorials on fixing popping/crackling noise but none did the trick. There's not much tuts on Dolby Audio online, either. The only way to solve the problem is to turn off Dolby Audio but the resulting audio quality is very intolerable.

I have an Acer Predator Helios 300, recently bought from Amazon. Didn't expect a new laptop would have a problem like this.

Please help me solve this problem. Thank you so much in advance.

>>Windows 10 has a built-in troubleshooter to check and fix issues with Sound. I would suggest you to run this troubleshooter to check if the issue is with your Audio. Press Windows key +X, select Control panel. Change the view by option on the top right to Large icons

Click on troubleshooting and click on the view all option on the left panel. Run the playing Audio troubleshooter

>>If not working, reinstall the audio driver.

Right-click on the Start button in the taskbar area and then click Device Manager to open the same. In the Device Manager, expand Sound, video and game controllers.  You should now see your audio driver name. Most likely you have Realtek High Definition Audio.

Right-click on it and then click Uninstall device option. You will now get the following confirmation dialog. Select Delete the driver software for this device checkbox and then Yes button when you see the confirmation dialog to go ahead and uninstall the device driver.

Restart your computer once and windows hould automatically restore the driver.

>>And if that didn't work, try using the generic audio driver that comes with Windows. Here's how:

Open Device Manager, right-click (or press and hold) your audio driver > Update driver software... > Browse my computer for driver software > Let me pick from a list of device drivers on my computer, select High Definition Audio Device, select Next, and follow the instructions to install it.

>>You can also install the Dolby audio directly from the downloaded driver file. Open the downloaded folder and you will find a DS1 folder.
Open the DS1 folder and openx64 folder and run the Dolby Digital application file.
