Using realtime mode, In previewing agent, when press start call, their is no intro or response from any of the available voice options. Note that the same instructions work fine in the STT-LLM-TTS option.

I was able to reproduce what you were seeing if I had some issue with my XAI key. If you deploy your agent, you should be able to see the agent logs when it runs that should give you some clue as to the failure: Agent commands | LiveKit Documentation
