Hello Vishal, let me help you with this. I can provide you with some documents about the topic.

Doc:

  • Possible Causes & Fixes
    Verify Live Link Plugin Activation
    Go to Edit → Plugins and ensure that Live Link and Live Link Face are enabled.
    Restart Unreal Engine after enabling them.

  • Check NVIDIA Audio2Face Setup
    Ensure the Live Link plugin is active in NVIDIA Audio2Face settings.
    Verify that Live Link streaming is enabled and that it points to Unreal Engine.

  • Ensure MetaHuman Blueprint is Configured Correctly
    Open your MetaHuman Blueprint and check if Live Link Face Component is added.
    Assign the correct Live Link Subject Name from the Live Link panel.
