We are trying to use the the playTone API on the Media Manager class to play tones on the device as follows:
 
Manager.playTone(ToneControl.C4 + 12, 1000, parameters.volume);
 
It does play a tone but always seems to play it at the same volume even though we have tried various values from 0 to 100.
 
On the call today Conrad mentioned that there was a concept of minimum volume that is controlled by the administrators - is it possible that this is preventing the application from requesting a lower volume, or is it possible that it is a firmware bug?
