This change makes sure that the VOICE_CALL stream volume tracks the BLUETOOTH_SCO stream volume when SCO audio is enabled. The down link audio volume now reflects what is being displayed when pressing volume hard keys on the device while in a video chat with a BT SCO headset. Volume settings on the headset and the device are still independent as we do not support handsfree profile yet. Change-Id: Ie0d2714730ea359b9318b9cbe6f0b2557ef0f976
