Webex on Citrix: Physical Webcam Displayed, but not NVIDIA Broadcast Virtual Cam (from Host)

If you are experiencing an issue where your physical webcam is displayed in Webex on Citrix, but not the NVIDIA Broadcast Virtual Cam from the host, there are a few troubleshooting steps you can try to resolve the problem.

Step 1: Check Compatibility

First, ensure that your system meets the minimum requirements for using the NVIDIA Broadcast Virtual Cam. It is important to note that the virtual cam feature requires an NVIDIA graphics card that supports CUDA 9.2 or higher. If your graphics card does not meet this requirement, the virtual cam may not be available or may not function properly.

Step 2: Update Graphics Drivers

Outdated or incompatible graphics drivers can often cause issues with virtual cam functionality. To resolve this, make sure you have the latest graphics drivers installed on your system. Visit the NVIDIA website and download the latest drivers for your specific graphics card model. Once downloaded, follow the installation instructions provided by NVIDIA to update your drivers.

Step 3: Check Webex Settings

Ensure that the virtual cam is selected as the default camera in the Webex settings. To do this, follow these steps:

1. Launch Webex and sign in to your account.
2. Click on the "Settings" gear icon in the top-right corner of the Webex window.
3. In the settings menu, select "Video" from the left-hand side.
4. Under the "Camera" section, check if the NVIDIA Broadcast Virtual Cam is listed as an available camera option. If it is not, try restarting Webex and your computer.
5. If the virtual cam is listed, select it as the default camera.

Step 4: Restart Webex and Citrix

If the issue persists, try restarting both Webex and Citrix. Close all instances of Webex and Citrix, then relaunch them to see if the virtual cam is now recognized.

Step 5: Reinstall Webex and NVIDIA Broadcast

If none of the previous steps have resolved the issue, you may need to reinstall both Webex and NVIDIA Broadcast. Follow these steps:

1. Uninstall Webex and NVIDIA Broadcast from your computer.
2. Restart your computer.
3. Download the latest versions of Webex and NVIDIA Broadcast from their respective websites.
4. Install Webex first, following the installation instructions provided.
5. Once Webex is installed, install NVIDIA Broadcast.
6. Restart your computer again and launch Webex to check if the virtual cam is now working.

If you have followed all of these steps and are still unable to see the NVIDIA Broadcast Virtual Cam in Webex on Citrix, it is recommended to reach out to the official support channels for further assistance.
