Lsherm,
Thank you so much for reaching out. I am Iggy, an independent advisor, and glad to assist you today with this issue.
The HDMI/DisplayPort audio is embedded in the GPU's driver bundle. If you recently upgraded to WIn11 please follow the steps below. You just need to install the latest drivers for your GPU.
Here’s how to do it depending on your GPU vendor:
- Download the Correct Driver Package
For NVIDIA:
- Go to: https://www.nvidia.com/Download/index.aspx
- Select your GPU model, download the latest Game Ready Driver (GRD)
- During install, select Custom (Advanced) > Check HD Audio Driver
For AMD:
- Go to: https://www.amd.com/en/support
- Download the latest Adrenalin Edition for your GPU
- The installer includes AMD HDMI Audio Driver
For Intel (UHD/Arc/Xe):
- Go to: https://www.intel.com/content/www/us/en/downloa...
- Download the latest Intel Graphics Driver for Windows 11
- This includes the Intel Display Audio driver
- Clean Up with DDU (Recommended if Issues Persist)
- Download DDU (Display Driver Uninstaller)
- Boot into Safe Mode
- Run DDU > Select GPU vendor > Remove everything
- Reboot normally and reinstall the driver from step 2
- Verify Installation
After installation:
- Open Device Manager
- Expand Sound, video and game controllers
You should see:
- NVIDIA High Definition Audio
- or AMD High Definition Audio Device
- or Intel Display Audio
Let me know once done so I can further assist you.
Regards,
Iggy
