Bang and Olufsen speakers fade in and out, and left and right.

[Rmulo]

I saw from another post that the problem is most likely due to a calibration issue. I have tried everything from updating drivers, setting them back to factory, uninstall + reinstall. But nothing has worked. 

This is the thread that I was talking about. 

https://h30434.www3.hp.com/t5/Notebook-Audio/B-amp-O-sound-decrease-continuously-to-no-sound-when/td...

It seems that I need access to the ClearRO.exe, but when I inputted the password and username from that thread, I received an error message. Could I obtain updated credentials or access to the ClearRO.exe file as well as guidance on how to fix this issue?

Thank you for your help!

Welcome to HP Community

I have gone through your Post and would like to help

The credentials and link  for the ClearRO.exe,does not work anymore.

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.

Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

Keep me posted how it goes

Thank you and have a wonderful day 😊

I too have this issue, and all of the troubleshooting steps have failed to resolve the issue.    A set of headphones will work fine, but the speakers are doing the same thing the OP posted.

@cartmang please try the below steps:

1. Go to Windows Device Manager > Sound, video and game controllers section.
2. In the list of audio device drivers, look for Realtek High Definition Audio or Conexant (depending on what driver you have).
3. 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.)
4. Right-click and select Update Driver Software.
5. Select Browse my computer for driver software.
6. Select Let me pick from a list of device drivers on my computer.
7. 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.
8. In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
9. At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
10. 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.
11. At the prompt to reboot, click Yes.
12. Enjoy your music now with no compression

P.S: Welcome to HP Community 😉

Keep me posted, as I (Or a trusted colleague) shall follow-up on this case to ensure the concern has been addressed, 

And your device is up and running again, only in case you don't get back to us, first! 

That said, If the information I've provided was helpful, give us some reinforcement by clicking the solution and kudos buttons, 

That'll help us, and others see that we've got the answers!

Good Luck.

Unfortunately switching to the Microsoft High Definition Audio Device didn't resolve the issue.  Same thing.  Volume starts out fine for 5-10 seconds, then fades to barely audible for 5-10 seconds, then comes back strong, over and over.    If I plug in headphones, no issues through the headphones.

To confirm, my laptop is a 2017 Spectre 15 with B&O sound (15t-bl000 CTO)

@cartmang We may need to update the driver to specific Windows version, and here's what I'll need so I can suggest you the best solution depending on it:

1. Select the Start button > Settings > System > About . Open About settings.
2. Under Device specifications > System type, see if you're running a 32-bit or 64-bit version of Windows.
3. Under Windows specifications, check which edition and version of Windows your device is running.

Provide the version of the Windows you have, is it Windows 10, 1703 or higher?

Keep me posted.

I have Windows 10 Pro, 64 bit

Version 2004

OS build 19041.450

[Riddle_Decipher]

@cartmang Unfortunately, HP hasn't released any updates for your version of windows, hence you may need to downgrade to an earlier version of windows, and disable automatic updates to avoid updating the same until the new driver for v2004 is available.
