Hi @sammj1969,

Welcome to the HP Support Community. 

I'd be happy to help you! 

It sounds like your HP Pavilion x360 2-in-1 laptop is experiencing an issue where the Bang & Olufsen (B&O) speakers are no longer being recognized by the system, and instead, the sound is being output through the generic Realtek audio drivers. This could be due to a driver issue, a software conflict, or even a hardware malfunction. Here’s how you can troubleshoot and potentially resolve the issue:

1. Check Device Manager for Missing Drivers

• Open Device Manager:
  • Right-click on the Start button and select Device Manager.
• Expand "Sound, video and game controllers":
  • Look for any yellow exclamation marks or red Xs next to the audio devices.
  • If the B&O speakers or related audio device isn’t listed, it might indicate a driver issue.

2. Reinstall the Audio Driver

• Uninstall the Current Audio Driver:
  • In Device Manager, right-click on the Realtek High Definition Audio device and select Uninstall device. Check the box that says Delete the driver software for this device and then click Uninstall.
• Restart Your Laptop:
  • After uninstalling the driver, restart your laptop. Windows should automatically reinstall the audio drivers.
• Download and Install the Latest Driver:
  • Go to the HP Support website and download the latest audio drivers specific to your model. Make sure you choose the driver that supports the Bang & Olufsen speakers.
• Install HP Audio Control:
  • HP Audio Control might be required to enable the B&O features. Ensure this software is installed and up-to-date.

3. Update or Roll Back Windows Updates

• Check for Recent Windows Updates:
  • Sometimes, Windows updates can cause hardware issues. Go to Settings > Update & Security > Windows Update and see if there have been any recent updates.
• Roll Back Recent Updates:
  • If the problem started after a recent update, try rolling it back. Go to Settings > Update & Security > Recovery and select Go back to the previous version of Windows 10/11 (if available).
• Pause Updates:
  • If rolling back solves the issue, consider pausing updates until a fix is confirmed.

4. Run the Windows Audio Troubleshooter

• Open the Troubleshooter:
  • Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
• Run the "Playing Audio" Troubleshooter:
  • Follow the on-screen instructions to see if Windows can automatically detect and fix the problem.

Please find the remaining steps in the next post.

Hi @sammj1969 

Please find the remaining steps below.

5. Check Audio Output Settings

• Right-click on the Speaker Icon:
  • Located in the taskbar, select Sounds.
• Set the Correct Playback Device:
  • Under the Playback tab, ensure the correct audio device is set as the default (it should list the B&O speakers if they’re detected).
• Test the Speakers:
  • Select the speakers and click Test to see if they produce sound.

6. BIOS/UEFI Update

• Check for BIOS/UEFI Updates:
  • Visit the HP Support website and see if there’s a BIOS update available for your model. Sometimes, a BIOS update can fix hardware detection issues.
• Update BIOS Carefully:
  • Follow the instructions on the HP site carefully to update the BIOS, as incorrect updates can cause other problems.

7. Reset or Reinstall Windows

• Reset Audio Settings:
  • If the issue persists, consider resetting your audio settings to their default configuration.
• Reinstall Windows:
  • As a last resort, you can perform a clean reinstall of Windows. This will remove any software conflicts that might be causing the issue, but make sure to back up your data first.

8. Hardware Check

• Physical Connection:
  • While rare, a loose connection inside the laptop could cause the speakers to disconnect. If you're comfortable opening the laptop (or if it's under warranty, have a technician do it), check the connections.

If none of the above steps work, the issue might be hardware-related. Contact HP Phone Support for further assistance.

Hope this helps! Keep me posted for further assistance
