Halo Reach Firefight glitch?

Whenever i play firefight score attack i always have Buck as my firefight voice but my character wont say anything whatsoever. Why is that? I asked all my friends before coming here.

I don’t think this is in the right forum. Also Im not sure why, maybe he has laryngitis.

Have you tried to change your firefight voice ? -_-

For the Firefight voice to work, all players in the game need a hard drive including you.
