I put them on generally, at least for the sake of dialogue. Not really sure why, I think I'd just prefer knowing for sure what was said.
On some games, like say "Left 4 Dead 2" I'll put additional subtitles on so I can know for sure what's going on - in L4D2's case Special Infected spawns, howls etc.
