Thank you for sharing your setup and troubleshooting steps. Since recent updates changed voice compatibility and model support, could you please confirm if switching to one of the newly supported voices (such as "ash", "ballad", "coral", "sage", or "verse") with your current model restores voice output? This will help determine if the issue is specific to the "Echo" voice after the update.
Tip: The latest documentation notes expanded voice compatibility for realtime models, so testing with a different supported voice may clarify if the problem is voice-specific or model-related.
