Realtek Drivers and fading sound

[nooty51]

I have a frequently recurring problem according to the many forums I have looked at in that on my Laptop Model no 15-au172sa, when trying to watch Youtube or iPlayer or indeed anything else,  the sound fades after about 10 seconds. It is infuriating. As advised on several HP forum threads I have deinstalled, reinstalled and updated software and settings until I am blue in the face! None have worked and I am irked that I have spent £500 on a laptop that fails to perform this basic function.  Please do not direct me to Realtek downloads, I have wasted more of my life than is reasonable downloading them and they have all failed to resolve this apparently basic issue. Please HP give us a sensible solution that works or I will be all over every review site there is giving you negative feedback. This is utterly unacceptable and I should probably go to Trading Standards- you are selling a product that does not do what it is sold to do and I cannot afford to spend this much money  to have it not work.

Hi! @nooty51, Welcome to HP forums.

I understand when you play an audio from your PC the volume fades automatically.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your laptop?

Please provide the product number of your PC to assist you better.

As you mentioned when you play an audio from your PC the volume fades automatically.

Please try the steps recommended below.

Go to Control Panel -> Devices Manager -> Audio, Video and Games Controllers

And find there Realtek audio card. Click on it with the right button of your mouse and choose ' Properties '.
Select ' Driver ' tab and select Roll Back Driver check if the issue persists.

Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for Realtek High-Definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
Right-click and select Update Driver Software.
Select Browse my computer for driver software.
Select Let me pick from a list of device drivers on my computer.
You should see a window that says Select the device driver you want to install this hardware. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Realtek High-Definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

Is the loudness equalization off? If not, please:
Right, click the speaker icon
select 'Playback Devices'. 
Highlight the default device
Click Properties
Click Enhancements tab
Next to 'Loudness Equalization' take out the check mark in the box.
Click Apply
Click OK

If the issue still persists uninstall the audio driver from device manager and install the drivers using HP recovery manager.

Refer this article to know how to restore drivers using HP recovery manager.

If the issue still persists after trying out the steps it is hardware issues with your PC.

Please contact HP support for service options.
