Questions about AX pro 5.1 headphones (mostly playstation 3 oriented)

Hey guys, just got these headphones and I am wondering if you have to change some settings ingame? For example when I fire up battlefield 3, do I have to change settings ingame to make the 5.1 to work or does it work automaticly? I also have a question about how to configure the speakers. I've seen people write that "have rear at 3" or "center speaker light blue" ect. How do I see this? Mine's orange all the time, how do I know how loud my speakers are?
I have changed to optic in settings with the ps3 and checked dolby digital 5.1 Ch.

Thank you for your responses.

Edit: Alright the I figuered out the volume part (colours and levels) I was stupid enough to use the Voice volume rod instead of master volume (duh). Although my other question still remains, I play more games then battlefield 3 so if someone with these headphones know anything about sound settings ect. please share your knowledge with me! Cheers!

Edit2: I noticed that my master volume switch doesn't work. Anyone know how to fix it or should I go back to the store/send them to tritton?

Alright, I called support and I solved the issue about the controller. I havn't seen an answer for this anywere so I'll post it here. When you move the master volume rod down and it stops, press it a little more till it clicks. You won't break it, but that's how you solve it. Worked for me atleast. Apperently a lot of people are calling them about this issue but they don't have any tips for it on their website (stupid but what to do). Hope this helps! Cheers!
