No Audio Output/Driver for HP Pavilion x360 Laptop

[Marshjello]

Full product name is:

HP Pavilion x360 Laptop- 14m-dw0023dx

The OS version is Windows 10 Home 21h2. After a very recent update, it can no longer detect and audio output. Upon entering device manager it said no Intel High Definition Audio Drivers were installed and attempting to update via device manager gave no results. If anyone know where I can get a driver for this or some other fix it would be greatly appreciated.

Please perform a clean install Audio software/driver, this should help.

   (a) Download the following driver and save on your computer,
          https://ftp.hp.com/pub/softpaq/sp112001-112500/sp112452.exe

   (b) Go to Device Manager, Sound to uninstall sound driver (Realtek) and reboot,
   (c) Right click downloaded file and select Run as administrator,
   (d) Reboot again.

Regards.

Thanks for the help, unfortunately there seems to be a problem with installing and deleting drivers as the corrupt one reappears after deleting and rebooting. The problem Driver is labelled as Other Devices and named Intel High Definition Audio(Error code 28). Would you know what to do?

I found the issue. If you are experiencing the same problem as me, open Device Manager and expand the System Devices drop-down. The issue was an outdated Intel Smart Sound Driver it seems and once that was updated the problem was fixed.

Hope this helps someone else as well.

Hello, how was you able to fix the outdated Intel Smart Sound Driver? I have a HP pavilion x360 as well that runs on Microsoft Window 10 (64-bit) and I'm experiencing the same problem like you had. The same person, BANHIEN, that helped you out, told me to install Realtek audio drivers from the Intel website since updating to a new OS (Windows 11), that the older OS (Windows 10) audio drivers won't be supported afterwards.

If you go into Device Manager and double click on the problem system, it should give you an option to automatically update its drivers which fixed it for me.

Windows 11 installed years back, immediately after was available.

All was working well. resent update result in audio failure. There is no device installed and can not be fix with drivers from Microsoft update site or manually. When connect external speaker sound is ok.

Latest updates were beginning of May 2023, device drivers.

Does any one cen help?

Thank you a million for posting this solution.  It fixed my absent internal speakers and microphone, plus missing Bluetooth mic, issues that I've been having for months.  I thought it was a hardware issue, as both HP's and Microsoft's automatic problem scanners could pick up no issue.  Now that you showed the issue is in some Intel system driver that didn't update properly, I now recall back that the last time things were working, my PC was running very hot (meaning it was doing an update).  Then the audio stopped.  HP and Microsoft (and Intel): you should be ashamed.
