When someone is talking ingame, it seems like it doesn't give the sounds enough time to finish. A character will start a sentence and then cuts it off after about 3-4 seconds. You probably don't understand so here is an example.
So I walk up to Mac and he starts talking to me,
"There is a MG down the street that been-"
"You need to take it out-"
"This is the first time I'm putting two-"
"Its a lot to take in."
This only seems to happen with BiA, then only other game I've tested it Half-Life2 and I don't have this problem.
If it still doesn't make since I will try and find a way to elaborate more.
