Sound fades in and out (only when playing built-in speakers) - HP ENVY x360 - 15m-bp111dx

HP Recommended
HP ENVY x360 - 15m-bp111dx
Microsoft Windows 10 (64-bit)

I've had this problem for a couple years...probably since the notebook was new.  The audio volume thru the built-in speakers will fade out to maybe 25% of the set volume, and then fade back in...the fade is usually abrupt...or might take a few seconds...and then the cycle repeats every minute or two. 

 

I've updated, uninstalled, reinstalled, the audio drivers, a few times (from my notebook's HP download page)...even tried a couple from different notebooks (all Realtek cards)...nothing works.

 

Bluetooth audio, and the headphone jack, work fine.  So perhaps the audio driver is not the problem?  As wouldn't ALL audio outputs be affected if the audio driver itself was at fault?  So perhaps it's the amplifier to the speakers?

 

Anyway...posting here for some help...and hoping it's the audio driver.

 

Thanks...

@wsalopek Welcome to HP Community!

 

I understand that you are getting sound fades in and out (only when playing built-in speakers).

 

Do not worry. I will try to fix the issue.

 

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.

 

https://ftp.hp.com/pub/softpaq/sp87501-88000/sp87889.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.

 

https://ftp.hp.com/pub/softpaq/sp87501-88000/sp87926.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 the windows fully load for a few minutes before checking.
