Comment(by eben):

 Replying to [comment:5 tomeu]:
 > Maybe we should have those controls in the device side of the frame. I
 think people right now are a bit disoriented because an activity can lower
 and mute the capture device and other activities cannot record any more. A
 control per activity wold fix it, but we probably cannot expect all
 activities will do the right thing.

 Right, that's what I'm suggesting with the camera and mic devices. I think
 that's really the best solution.

 I don't think the ability to set this globally should preclude the ability
 for activities to have their own input gain adjustments. I'm not sure I
 understand what you're saying about one activity preventing another from
 recording. The global input level should be just that; activities
 shouldn't have control of the master volume slider. They should only be
 able to adjust the gain on the signal once they get it at the master
 volume.
