This issue is for a: (mark with an x)

- [ ] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [x] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

call_connection_client = acs_client.get_call_connection(call_connection_id)
await call_connection_client.start_media_streaming(
operation_callback_url=callback_uri,
operation_context="startMediaStreamingContext"
)

Any log messages given by the failure

Expected/desired behavior

I have played an audio source to the user once the call has been connected I started the media streaming so that I can send the audio to AI for assistance . but it is not happeing. this is my main code
