[text-to-speech] Using AudioFormat PCM in method synthesize throws exception accept=audio/l16, status: 406, error: rate parameter missing in mimetype audio/l16

[roymitchley]

I am trying to call the text-to-speech synthesize method with AudioFormat.PCM. This is giving me the exception accept=audio/l16, status: 406, error: rate parameter missing in mimetype audio/l16
com.ibm.watson.developer_cloud.service.exception.ForbiddenException: rate parameter missing in mimetype audio/l16

I can not see a way for me to pass the rate parameter as the method parameter for synthesize is a AudioFormat type that is a numeric.

It looks like a similar problem has been solved for speech-to-text service.
