How Do I Enable or Disable HDMI Audio in Windows If I Am Using an HDMI Connection Between My Nvidia Video Card or Motherboard and My Monitor?

The latest Nvidia GeForce drivers allow you to enable or disable HDMI Audio through the Nvidia Control Panel. You may want to use this for several reasons. First, this option will allow you to use headphones or speakers connected to either the onboard audio panel or your front panel, even though you are using the SPDIF pass-through audio connector, by simply turning the HDMI audio to disabled.

Likewise, you can switch back to the SPDIF pass-through when finished with your headphones or speakers by switching the HDMI audio to enabled. Second, this option is available for each monitor or TV you have attached, so you can enable or disable the HDMI Audio to each monitor or TV you are using. Third, this will help solve conflicts between using a onboard sound and HDMI pass-through audio. Finally, this option is located in a very convenient location to quickly change settings to suit your audio needs.

To use this option:

1. Ensure that you are using a video card or motherboard with an onboard video that supports the use of an HDMI. For a list of EVGA video cards and motherboard onboard video controllers that support HDMI, please see: https://www.evga.com/support/faq/?f=57989 2. Begin with your system off. Detach all monitors and TV's from the video card or the onboard video controller. 3. If you do not wish to use the SPDIF to HDMI pass-through, then skip this step. If you do wish to use the SPDIF - HDMI pass-through, then please see this FAQ for instructions on installing the SPDIF cables to your motherboard: https://www.evga.com/support/faq/?f=58021 4. Depending on your video card or onboard video controller, locate either the direct HDMI outlet or a supported DVI to HDMI adapter. If using the DVI to HDMI adapter, carefully attach the adapter to the video card, and hand-tighten the screws to secure the adapter. 5. After locating the adapter-type, plug in an HDMI cable to the graphics card or the onboard video controller, then plug in the other end of the cable to an HDMI-compliant monitor or TV. Ensure that the only monitor or TV attached to the video card is the one using the HDMI cable. 6. Turn the computer on, and watch to see if the monitor or TV displays picture. If not, check to make sure that the cable connections are secure and that the monitor or TV is set to the proper signal - HDMI. 7. After booting into Windows, download the latest drivers for your graphics card(s) or your onboard video controller. 1. For EVGA products go here: https://www.evga.com/support/drivers/ 2. For all other other Nvidia based cards and motherboards: https://www.nvidia.com/Download/index.aspx?lang=en-us 8. Upon completing the driver installation, Windows may ask you to reboot. If it does, follow the prompt and reboot. 9. In the Windows Sound settings, make sure your TV or monitor is selected as the Primary Output Device and has a green checkmark on the icon, then either start a new audio file or restart your currently playing audio file to verify your sound is working. My computer hangs, freezes or becomes jumpy after installing drivers for my 400/500/600/700 Series Nvidia GeForce card.

This issue can be caused by a conflict with the on board audio controller on your new Nvidia card and your motherboard's audio controller. You can try the following uninstall method which will fully disable the audio controller and should help eliminate the issues you are experiencing.

1. In the Control Panel, go into the Device Manager. Expand "Display Adapers" and right click on the 400/500/600/700 series card, and select "Properties". In the tab named General, look for the entry called "Location". It should read, for example, "PCI_Bus_1, device 0, function_0". If using multiple cards please check and note each listing.

2. Go under "System Devices" and scroll down the list until you see "High Definition Audio Device". There should be at least two entries, possibly more if you have multiple video cards or a sound card. Check them under "Properties" as you did with the video card to see which one matches your the PCI Bus location. Disable (not uninstall) the one that matches your video card.

3. Look under "Sound Devices" and it should no longer list the Nvidia High Definition Audio Controller (this step might or might not require a restart).

After restarting, a clean install of the Nvidia drivers is highly recommended. This can be done by running the latest driver package, choosing "Custom installation", and checking the box labeled "Perform A Clean Install". This will will remove the previous drivers and re-install them rather than over-writing the existing drivers. Why does my EVGA graphics card run hot?

Graphics card temperatures typically range from 30°C to 40°C at idle and from 60°C to 85°C under load. Most high end video cards typically have a maximum temperature between 95°C- 105°C, at which point the system will shut off to prevent damage. A video card is not considered to be overheating until it exceeds 90°c under load.

You can see the maximum temperature of a specific video card on Nvidia's Hardware page for that card here: HERE. Choose your graphics card with "More Info", then click "SPECS and then "View Full Specs" to get the "Maximum GPU Temperature (in C)" for that card.

Many things can affect your graphics card's temperature. The ambient temperature in the room, the number of fans in your system along with the airflow layout, how many components are in the system, dust buildup on the card and in the heatsink/fan, and the speed of the graphics card fan all directly affect your temperatures. Ensuring you have enough fans for your case and that your cables are neat and out of the way along with dusting your system with canned air on a regular basis can help keep your temperatures down.

If you are not sure if you have a good airflow layout, test your card with the side panel removed. Removing the side panel will ensure that sufficient ambient air reaches the card to allow it to cool properly. If you notice 3-4C or greater of temperature drop, under load, then the airflow in the system can likely be improved.

You can use our Precision XOC software to manage and control your fan speed by setting the fan to run at a higher speed or by creating a custom fan curve to keep temperatures lower. You can get Precision XOC: HERE.
