There's a lot of research on this topic - depending on which study you cite, the visual sense is the dominant sense in 60-85% of the population, followed by auditory, then physical.
In every study I've seen Visual wins out at about 2:1 over Auditory, or more. This doesn't mean these people don't care about audio, just that video is more important.
My dominant sense is visual, yet I'm more fussy about my stereo than my display, prefer music to movies/tv, and music is a big part of my life. Still, I think there's a reason that movies outsell "books-on-tape".
