Bang & Olufsen missing equalizer

HP Recommended
Envy x360 Convertible 15
Microsoft Windows 10 (64-bit)

I've search the board on this issue and read that to get the equalizer back is to install the latest realtek sound driver from the HP Recovery Manager (sp 79899 exe), but it didn't work. I still do not see the equalizer after I restarted my computer


Please help

@Diah_89- Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support and we appreciate your patience.

That said, Please try the steps recommended below.


Try updating the BIOS and audio drivers to the latest version from the links below and check if it helps.

Update the BIOS using this link. Click Here

Also, update the audio drivers using this link. Click Here

Go to Windows Device Manager > Sound, video and game controllers section.

  • In the list of audio device drivers, look for Realtek High-Definition (HD) Audio. This is the device driver for Beats Audio (but should work for Bang & Olufsen as well).
  • 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 Realtek High-Definition (HD) Audio.

At the prompt to reboot, click Yes.
