Modalities not working

[Sophon]

I want the Realtime API to not only send the audio response but its text form too.

So I configure the modality:

OpenAIRealtimeSessionConfig(modalities = listOf("audio", "text")

And then I await the bot's response's transcription in this callback function, but none of the callback functions work - I tried onBotTranscript(), onBotLLMText() and onBotTTSText() - but none of those return the transcription of the response.

onUserTranscript() works properly.

Expected

• (user voice input): Who is snow white?
• onUserTranscript: Who is snow white?
• (one of the bot transcription callbacks): Snow White is a classic fairy tale character known for her beauty, kindness...

Actual

• (user voice input): Who is snow white?
• onUserTranscript: Who is snow white?
• (one of the bot transcription callbacks): no data

Is this a bug or am I configuring the client wrongly?
