Thanks, but that didn't help. I really appreciate all of your help.
I've been trying to really figure what the problem is and how best to describe it. At first I thought it was a setting issue, but now I don't. It's pretty clear that it's in the game. When my character is being briefed, the sound is usually fine, and when i'm in an elevator I can barely hear it. Additionally, when there is a cut scene with dialogue in it, the sound goes down too. It's really annoying. There are other instances where there are problems that I need more time to fully identify.
Again, I really appreciate your help!
