This is a short term solution to change the volume of a RTCAudioTrack (which contains an RTCAudioSource property) until applyConstraints for RTCMediaStreamTracks has been implemented. This CL adds one new Objective-C method to AudioSourceInterface's wrapper: -(void)setVolume:(double)volume BUG=webrtc:6533, webrtc:6805 This is my first CL for Chromium/WebRTC, so please let me know if I did something wrong.
