Lenovo B50-70 crackling sound

I have a Lenovo B50-70 laptop, with Windows 8.1 64bit, with all drivers installed from Lenovo's support site.
When i listen music or watching video, periodically the audio sound crackling/creaking.
Can be this caused by driver problem ?
 
Thank you for help!

Hi bzoli,

 

Welcome to Lenovo Community Forums!

 

There is a setting that cause this issue,

Can you try disabling the sound enhancements

This guide is for a WIndows 7 OS but pretty much the same with 8 and 8.1

 

Hope this helps

Cheers!

Thank you for your help.

But on the "Speakers Properties" window, i have no "Enhancements" tab, so i can't "Disable all enhancements".

Hi Bzoli,

 

Try connecting an earphone and check if the issue persists.

 

Also try to uninstall the driver and check in windows generic driver.

 

Hope this helps. Do post back if the issue persists!                                                   

 

Best regards,

Hi bzoli,

 

It seems that the Audio is running in a Generic Driver,

 

Try running this driver and check if that will change the settings

Realtek Audio Driver

 

 

Hope this helps

Cheers!

hi bzoli,

 

Is it happening on any video or audio file, Sometimes the Audio you are playing really has that sound.

 

Also, after you install the Audio driver again, Try checking the enhancements tab using the guide i posted earlier.

Maybe post some screenshot if still no enhancement tab.
