Solved!

Volume decreases ,and increases automatically

HP Recommended
hp pavilion 15-au172nb
Microsoft Windows 10 (64-bit)

I have a brand-new HP Pavilion. Every time I play sound - youtube, mp3, mp4, ... - the sound decreases automatically after some time (5 seconds or so), and increases again, allthough volume remains at 100%. After I pause  and push play, the sound is back at top volume for a couple of seconds, and then it decreases again. So it constantly fluctuates.

I have checked the audio-settings, but I can't seem to find a solution there.

Hi,

 

Try the following.

 

Download the Realtek HD Audio installer on the link below and save it to your Downloads folder.

 

http://ftp.hp.com/pub/softpaq/sp80501-81000/sp80538.exe

 

When done, hold down the Windows key and press R

 

Into the Run window, type devmgmt.msc and hit enter.

 

In Device Manager, expand Sound, Video and Game Controllers.  Right click the Realtek device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.

 

When complete, download and reinstall the Chipset driver on the following link.

 

http://ftp.hp.com/pub/softpaq/sp78001-78500/sp78355.exe

 

When the Chipset reinstallation has completed, restart the notebook.

 

When windows has reloaded, open your Downloads folder, right click on the Realtek installer and select 'Run as Administrator' to start the installation.  When this has completed, restart the notebook again and let windows fully load for a few minutes before checking.

 

Regards,
