HP ENVY All-in-One - 32-a0014 Bang & Olufsen Speakers Won't Work

[JustJack22]

My speakers were working until I had to unplug my computer to move it. When I turned it back on, there was no sound coming from the speakers. I tried to use the 3.5mm jack but it did not work either. Then I tried the USB jack and it did work, the headset, and the mic.  I ran every test and they did not find any issues.  I've downloaded and updated the audio driver and BIOS. The outsourced HP Tech support said that the only solution was to do an HP cloud recovery. I do not believe that is necessary because when I had the "audio output device not installed" issue, that is the same thing they wanted to do, but I found a solution that worked.  When I go to Device Manager, I see "High Definition Audio Device" and "Intel(R) Display Audio" for my drivers.  When I google drivers for the Bang & Olufsen, I see Realtek High-Definition (HD) Audio Driver as the driver but I do not see it listed in my Device Manager.  I am wondering, Do I have the wrong driver(s) installed? Did I accidentally remove the Realtek High-Definition (HD) Audio Driver? Something other than a factory reset.

Hi

Not exactly sure what is happening. A "High Definition Audio Device" driver is usually a generic Windows driver.

Check this link for your PC's Realtek audio driver https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-envy-all-in-one-pc-32-a0000i/29051861/...

Bill,

I appreciate your willingness to assist. I tried downloading/installing the driver multiple times. It did not work.

HI

My pleasure.

Open Sound in Control Panel. The Playback tab should list Intel Audio and Windows High Def Audio or Realtek Audio if you could install the Realtek driver. The default would be High Def Audio or Realtek Audio using the 3.5 mm jack. It seems the PC is defaulting to Intel for some reason because you have sound when using the USB connection.

I don't know how you lost Realtek Audio and why cannot use Windows High Def Audio or why you cannot install the Realtek Audio drivers.

Have you run Diagnostics? Start the PC. Tap "ESC".

Select "F2". Run system and component tests. You could have a problem with integrated audio chip on the MB.

Sadly, the only way to isolate a hardware problem, unless diagnostics reveals a hardware sound problem or other hardware problem, is to back up data. Then do a HP Cloud Recovery. Same symptoms would indicate a MB audio chip hardware problem.

Hi

Forgot to add this:

Check system files for corruption before doing a cloud recovery. Open an Admin command prompt. 

Enter the following command: sfc /scannow

Or use Windows Update servers to repair system files with this command DISM.exe /Online /Cleanup-image /Restorehealth

Bill, I tried both but everything was good

Bill,

I really do appreciate all of your efforts. It hurt hearing "HP Cloud Recovery". but I might need to accept that as the solution....just not yet!!!

Hi @JustJack22 

My pleasure.

Yes, it is a pain to back up data and start from scratch.

I am out of ideas.
