What's wrong?

The audio guide shows how to receive delta.audio fragments, but does not include the terminal events of an audio response.

The streaming reference describes a terminal finish_reason repeated in the final usage chunk before [DONE]. Could the audio guide confirm how this applies to audio output?

Expected content

A complete streaming audio example showing the final audio chunk, terminal finish reason, usage chunk, and [DONE] marker would help.

Please clarify:

• Whether every successfully completed audio choice includes finish_reason: "stop".
• Whether a successful audio response can end with only null finish reasons followed by [DONE], and how clients should confirm completion in that case.
• Any model or provider differences clients should account for.
