That can be entirely left to the UA environment;  *how* the user's 
preference "I need captions if available" is expressed is (happily) 
out of scope for us.

Indeed, there are media resources which would like to be embedded in 
a page with options for turning things on and off manually, as well. 
We should probably also cover the case when the user's prefs change 
while something is playing.

I don't think pure manual selection every time is appropriate.  Those 
environments needing captions (for example) shouldn't have to do 
something special every time they encounter a video (and there may be 
several on a page).
