I'm pretty sure the way its set up now, the "all' setting only will play when your the home team, but if your playing against, say Florida, and you are Georgia, and you have sound for Florida, they will play even if your the away team.
however if you want to redownload the patch, you'll need clear the cache, then restart the game, it will redownload.
