Isses on 7.1 headset

[PeaceDealer]

Hello.

I own a Razer Tiamat 7.1 surroundsound headset, how-ever when I use the 7.1 features and listen to any youtube video, the sound is way off. If i disable 7.1 it sounds normal.

It feels as only the regular left and right stereo comes through. I'm using the built-in sound from my ASRock 970 Extreme3 R2.0.

Have i missed some settings somewhere? I have "speaker fill" enabled.

Have you enables bass management in your sound cards properties ?
