IMHO they belong into the device context to.
New problem: How to handle sound? For the video-related settings it is
quite clear: The driver will set them if the application goes to use the
video hardware, i.e. capture image(s) with read() or STREAMON+friends.
For audio it is'nt that obvious. There is - for example - no need to
touch TV sound if you switch the video input to the camera temporarely to
capture a image for your webcam...
