Audio controller driver missing from clean Win10 install - Not available on HP site(Envy x360, B&O)

HP Recommended
Envy x360 - 15z-ds100
Microsoft Windows 10 (64-bit)

I just received this 2020 Envy x360, and am starting with a clean installation of Win10 (free of ads and bloatware).  When everything is installed und updated, there is one device in Device Manager that does not have a driver.  It is listed as "Other devices/Audio controller".   This system has the Bang & Olufsen audio, and I'm not sure that the driver is installing correctly.  The drivers from HP's support site don't finish installing (they hang up when a Command window is open), and the driver revision is well behind the Realtek driver Windows automatically downloads.


I have tried to uninstall the automatically downloaded driver and install the HP driver, but the installation is still unable to complete.  On restart, the newer, questionable driver is reinstalled automatically.


Can anyone at HP (or otherwise) provide the correct driver for this audio controller?Annotation 2020-12-21 201601.png

I reviewed your post and I understand that you are facing issues with the audio controller driver.


Don’t worry, I assure you I will try my best to get this sorted.


I recommend you download and install HP support assistant from the below link and it will automatically install all the latest drivers available for your computer.


Here is how it is done.


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

    Click Updates in the My notebook pane

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

     Updates list in HP Support Center

  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.

  6. Perform any other update management actions as needed.

    • Postpone an update: Click Remind me, and then select a time preference.

    • Delete an available update: Click the Delete icon  to remove the update from the list and record it in the action log.

    • Review updates status: Click Action log below the list to view installed, postponed, or deleted updates.


Let me know how it goes and you have a great day!
