Summary
We are developing a real-time interactive MetaHuman application in Unreal Engine 5 deployed on an Azure cloud GPU virtual machine. The system integrates a conversational AI (Convai) to enable voice-based interaction between users and the MetaHuman character.
The application relies on microphone input captured through Unreal Engine’s standard audio systems (AudioCapture / VoiceCapture). While this setup works correctly on a local machine, the same configuration fails in the cloud environment, where no valid microphone input is detected or accessible.
On the Azure VM, Unreal initializes audio using a “Remote Audio” device, but microphone input is not captured or passed into the engine, preventing the AI system from receiving user voice input. As a result, real-time conversation does not function despite successful initialization of all other systems.
