Google-adk liveApi, how to pass audio to sub agents/tools

[pretbc]

Hello there,

Ive a question maybe some1 already tried:

I want to create root agent which will have agent as a tool (2x) and I wondering if there is possibility to pass input audio (from live_queue) to these tools rather then only TEXT

affect_alignment_agent = Agent(
model="gemini-2.0-flash-exp",
name="affect_alignment_agent",
description="Affect alignment agent",
instruction=affect_aligment,
)

engagement_agent = Agent(
model="gemini-2.0-flash-exp",
name="engagement_agent",
description="Engagement agent",
instruction=engagement,
)

affect_alignment_tool = agent_tool.AgentTool(agent=affect_alignment_agent) # Wrap the agent
engagement_tool = agent_tool.AgentTool(agent=engagement_agent) # Wrap the agent


root_agent = Agent(
model="gemini-2.0-flash-exp",
name="root_agent",
description="Root agent that coordinates the affect alignment and engagement agents",
instruction="""
You are responsible for coordinating the affect alignment and engagement agents tools.
Send user input to the tools and wait for their responses.
Combine the responses from the tools and send the final response to the user.
""",
tools=[affect_alignment_tool, engagement_tool],
)

what I can see from the log:

Raw response:
{"candidates":[{"content":{"parts":[{"text":"```text\nDetected Emotional State: Neutral (valence = 0.5, arousal = 0.5). Delta from baseline: No significant change.\nStrategy: Maintain a neutral and friendly tone as the user's emotional state is currently stable.\n\nResponse: \"Hello! I'm doing well, thank you for asking. How can I assist you today?\"\n```\n"}],"role":"model"},"finish_reason":"STOP","avg_logprobs":-0.13121765087812376}],"model_version":"gemini-2.0-flash-exp","usage_metadata":{"candidates_token_count":78,"candidates_tokens_details":[{"modality":"TEXT","token_count":78}],"prompt_token_count":1111,"prompt_tokens_details":[{"modality":"TEXT","token_count":1111}],"total_token_count":1189},"automatic_function_calling_history":[]}

Im not pretty sure that these response was base on AUDIO. It looks like it is base on TEXT only.

Is this possible to create custom runner with artifact_service=artifact_service and base on that other agents will be able to access AUDIO ?
