Windows 11 with the HDMI connection to an Onkyo receiver

THANKYOU SO MUCH, Francisco. Your advice is so clear and it worked.

Hi Francisco,

Thanks for your help. I followed all your instructions, but HDMI sound still not working.

( It works on my Dell XPS 15, where the driver "TX-NR609 (HD Audio Driver for Display Audio)" is present in Device Manager under Audio inputs and outputs

I uninstalled Intel(R) Arc(TM) Graphics and restarted and installed Intel@ Graphics Driver 31.0.101.5234

DEVICE MANAGER listings haven't changed.

Hello,

Windows routes HDMI sound through the graphics adapter rather than the Cirrus or Intel Serial IO drivers. In other words, you need to reinstall the display driver package that carries the "HD Audio Driver for Display Audio" component.

First, open Settings > System > About and note which GPU is listed under "Display adapters" (for example, Intel UHD Graphics or an NVIDIA/AMD card). Then go to the OEM’s support site, grab the appropriate Windows 11 driver from their download pages. Run that installer exactly as delivered by the manufacturer (it should detect and include the HDMI audio driver), then reboot.

After rebooting, make sure the Onkyo is powered on and the HDMI cable is firmly seated on both ends. Open Device Manager, click View > Show hidden devices, and expand "Sound, video and game controllers". You should now see something like "Intel Display Audio", "NVIDIA High Definition Audio" or "AMD High Definition Audio Device".

If it’s listed, right‐click and choose Enable if it’s greyed out. If it isn’t listed at all, go back into Device Manager, right‐click the display adapter entry under "Display adapters", choose Uninstall device (check the box to remove the driver files), reboot, then immediately install the driver package you downloaded. That forces Windows to re-detect the HDMI audio component.

Once the display-audio device appears, open Settings > System > Sound > More sound settings, and on the Playback tab you should see the Onkyo receiver listed as "Digital Audio (HDMI)" or similar. Right-click it, choose Enable if needed, then Set as Default Device. At that point sound should flow over HDMI into the receiver.

If you still don’t see it, try a different HDMI port on the Onkyo or a fresh HDMI cable and repeat the driver reinstall steps.

Let me know the results please!
