I've brought this up before but they refuse to implement this simple option.
I have had the same issue and unfortunately the only option for someone in your situation is to turn the dialogue volume down.
turn the volume down, put subtitles on
Is there an option for turning down only the speech or voices? I know in bad company they had that option.
I consider questions/comments like the OP to be extremely dense.
You bought a M-rated game. There's never going to be any option(s) to turn that off. It's a M-rated game.
Yeah I figured there wouldn't be an option. Bad Company 2 has the option to turn down character dialogue while still being able to hear effects and music, but I guess they leave out that option out for bf 3 and 4. Don't know why they wouldn't add a filter like on CoD, it would increase their revenue.
