Realtime API with Multiple Tool Calls Results in No Voice Output

[sibblegp]

Describe the bug

When the SDK uses multiple took calls which return JSON (in this instance asking for film times which calls to search for the film and then for times of that film_id near a location), there is no voice output. When I say something back to it to say "What were those times again?" then it responds.

See this trace: Imgur

Note there is no audio out after the tool calls.

Debug information

• Agents SDK version: v0.2.1
• Python version: Python 3.13

Repro steps

Setup chained tool calls that should result in an audio out. Instead, no audio is generated.

Expected behavior

An audio out should be generated after multiple tool calls in sequence.
