After Windows 11 V24H2 update, sound was gone.

[rem717]

After the 24H2 update of Windows 11 I had no sound. Windows troubleshooter did not help.  It just said there were no audio devices. The automated HP troubleshooter got sound back on Bluetooth, but the PC speakers and mic did not work. With the Bluetooth devices off it said the speakers and mic were disconnected. I had to roll back the driver on Intel Smart Sound Technology OED to get the PC sound working.  On the NVIDIA High Definition Audio events tab I have the message "Device HDAUDIO\FUNC_01&VEN_10DE&DEV_00A7&SUBSYS_103C8BA9&REV_1001\5&29a72739&0&0001 requires further installation."  That is on the date of the update. Should I be concerned about this? I did try updating the Intel driver again and had to roll it back. The NVIDIA  driver says it is working

Hi @rem717 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It looks like you've encountered an issue with sound functionality after the Windows 11 24H2 update, where the sound was lost for your PC speakers and microphone. This issue is related to drivers (specifically Intel Smart Sound Technology and NVIDIA High Definition Audio) and the sound card configuration.

Understanding the Problem:

• After the update, you were able to get sound working with Bluetooth devices but not with the built-in PC speakers or microphone.
• The Windows troubleshooter couldn't identify the issue, and the automated HP troubleshooter managed to restore Bluetooth sound, but the PC speakers and microphone were still not working.
• The error message on the NVIDIA High Definition Audio device indicates that the device requires further installation, which could mean that either the driver is not correctly installed or it needs an update to function properly.

Addressing Your Concerns:

You should definitely investigate the NVIDIA message you’re seeing, as it could be contributing to the audio issue, particularly if the message appeared immediately after the update. Let’s break it down:

Intel Smart Sound Technology Driver Issues:

• You mentioned having to roll back the driver for Intel Smart Sound Technology OED in order to get sound working for the PC speakers.
• This suggests that the new driver provided with the update is likely incompatible or causing issues.
• Recommendation: After rolling back, ensure that you are using the most compatible version of the Intel Smart Sound driver. You could try uninstalling the Intel driver completely and reinstalling the most recent official driver from HP or Intel's website.

NVIDIA High Definition Audio Error:

• The error message regarding HDAUDIO\FUNC_01&VEN_10DE seems to indicate an issue with the NVIDIA audio driver, which likely pertains to HDMI or NVIDIA GPU audio output.
• It’s possible that the NVIDIA driver was affected during the Windows update, leading to an incomplete installation.
• Recommendation: Try updating the NVIDIA driver to the latest version through the GeForce Experience app or the NVIDIA website. If the driver is already up to date, you may need to uninstall the current driver and reinstall it to ensure it's properly set up.

Step-by-Step Troubleshooting:

Update/Reinstall the Intel and NVIDIA Audio Drivers:

• First, uninstall the current Intel Smart Sound Technology OED and NVIDIA High Definition Audio drivers.
  • Go to Device Manager > Sound, video and game controllers > Right-click the Intel and NVIDIA audio devices and choose Uninstall device.
  • Restart your computer.

I hope this helps.

Take care and have a good day.
