Windows 11, Nvidia 3080, HDMI Video Works but No HDMI Audio Device Detected

If you've recently upgraded to Windows 11 and have an Nvidia 3080 graphics card, you might have encountered an issue where the HDMI video output is working fine, but no audio device is detected. This problem can be frustrating, but it's usually easy to fix. In this article, we'll cover the key concepts related to this issue and provide a detailed context on how to troubleshoot and resolve it.

Checking the Connections

The first step in troubleshooting this issue is to check the physical connections. Make sure that the HDMI cable is securely connected to both the graphics card and the Denon AVR-S960H receiver. If you have another HDMI device, try connecting it to the same HDMI port on the graphics card to see if the audio works with that device.

Updating the Graphics Card Driver

If the physical connections are fine, the next step is to update the graphics card driver. Nvidia frequently releases updated drivers that can fix issues like this one. To update the driver, follow these steps:

1. Press the Windows key + X and select Device Manager.
2. Expand the Display adapters category.
3. Right-click on the Nvidia 3080 and select Update driver.
4. Select Search automatically for drivers.
5. Follow the prompts to install the updated driver.

Checking the Audio Settings

If updating the driver doesn't fix the issue, the next step is to check the audio settings. Follow these steps:

1. Press the Windows key + X and select Sound settings.
2. Make sure that the correct audio output device is selected.
3. If the correct device is selected, try setting it as the default device.
4. If the correct device is not listed, click on Manage sound devices and make sure that it's enabled.

Updating the BIOS

If none of the above steps work, you might need to update the BIOS on your motherboard. This is a more advanced step and should only be done if you're comfortable working with low-level system settings. Before updating the BIOS, make sure to back up any important data and create a restore point.
