New Gemini Native Audio model failing for some languages

Gemini API

After switching to gemini-2.5-flash-native-audio-preview-09-2025 some languages are not working despite being documented as supported here: https://ai.google.dev/gemini-api/docs/live-guide

Specifically at least this language is failing: Arabic (Generic) ar-XA

This is the error received from the server when trying to enable that language: received 1007 (invalid frame payload data) Unsupported language code ‘ar-XA’ for model models/gemini-2.5-flash-native-audio-preview-09-2025; then sent 1007 (invalid frame payload data) Unsupported language code ‘ar-XA’ for model models/gemini-2.5-flash-native-audio-preview-09-2025

Thank you

Hi @ggarber
Please note that these native models are designed to automatically determine the response language and do not support explicitly setting the language code via the configuration. To enforce Arabic output, you must integrate the language requirement directly into the model’s instructions, such as by adding this to your prompt or system instruction: 'You are a helpful assistant and answer in a friendly tone. Reply in Arabic (Generic) ar-XA language’
Could you please attempt this approach and inform me whether the problem persists?.
Thanks
