Sound volume goes up & down

Product Name: Pavilion Notebook 15-au072sa
Operating System: Microsoft Windows 10 (64-bit)

I've had this laptop for a couple of months now but have only just got around to watching videos or listening to music on it. When I try to do this the volume fluctuates wildly goimg from incredibly loud to very quiet. Adjusting the volume control has no effect. It happens with every form of sound source whether it be from YouTube eg or off music downloaded onto the laptop. Is this more likely to be a software or hardware issue?

Re: Sound volume goes up & down

Hi,

 

Hopefully it's just a software issue, so you could 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/sp78501-79000/sp78936.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/sp76501-77000/sp76608.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,
