HP ENVY Bang & Olufsen speakers gritty noise

[woko]

The speakers on the unit make a quiet scratchy, gritty, crackly noise in the background when any audio is played out of them. Sometimes it gets quite loud and there is no way to stop it. I have updated the audio drivers and nothing has changed. This has been happening since I got the laptop about a year ago.

Thank you!

Hi! @woko, Welcome to HP forums.

I understand you have audio issues with your PC.

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

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

Have you connected an external speaker or headphones to your PC?

As you mentioned when you play audio from your PC you hear a crackling noise.

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

Try the steps recommended below.

Change Sound Format 

Right-click the sound icon at the bottom right corner of your desktop and select Playback devices.  

Highlight your default audio device, which should have a green tick on its icon, then click Properties. 

Go to the Advanced tab. Select from the drop-down box 16 bit, 44100 Hz (CD Quality). Then click Apply and OK to save the change. 

If CD Quality option fails to help you solve the popping sound issue, try to choose another audio format and see what happens.

Disable Sound Enhancement

Some sound drivers use enhancements to improve sound quality on your PC. But if enhancements aren’t working well, crackling sound issue could occur. To disable it: 

1) Right-click the sound icon at the bottom right corner of your desktop and select Playback devices.  

2) Highlight your default audio device, which should have a green tick on its icon, then click Properties. 

3) Go to Enhancements tab. Check the box for Disable all enhancements. Then click Apply and OK to save the change. 

Note that this option is not a universal one, since not all software drivers include such a function. You may also see a similar tab named Sound Blaster and similar effects. Or you may not see the option the disable enhancements at all. 

Also, Go to Windows Device Manager > Sound, video and game controllers section.
In the list of audio device drivers, look for IDT or 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 for 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 IDT or Realtek High-Definition Audio.
At the prompt to reboot, click Yes.

If the issue still persists try the steps recommended below.

background intelligent transfer service (BITS) transfers files (downloads or uploads) between a client and server and provides progress information related to the transfers. If the BITS service is turned off, windows update may have problems delivering files to your computer.

Start the BITS service click start, and then click run.

Type services.msc in the open box and then click ok.

Right-click background intelligent transfer service, and then click properties.

On the general tab in the startup type box, click Automatic, and then click apply.

In the service status section of the properties dialog box, verify that the BITS service is started. if it is not started, click start.

Click apply, and then click ok.

Also, uninstall the audio drivers from device manager and install the latest audio driver and BIOS on your PC using HP support assistant.

Windows Update is a utility that keeps your PC safe and your hardware drivers freshly updated.

1. Type “Windows Update” in your search box and click on “Check for updates”

2. In the Update & Security settings page, click “Check for updates”

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 try running a system diagnostics test from your PC and check if the hardware components on your PC are functioning correctly.

This seems to have helped for the time being, so thank you! However it is rather temperamental so I'm not 100% sure. Also, it has not stopped another speaker issue where the right speaker grill makes a very gritty fuzzy noise whether sounds is playing out of them or through headphones. This only happens occasionally but is rather loud and obviously very annoying. 

Thankyou for your help.
