Turtle Beach PX4 headset not working with CS:GO

[El Churro]

This is headset is made particuarly for the PS3/PS4 but, with a blue tooth adapter i was able to instal the drivers to my PC and now use it for gaming on here. My head set works in DAYZ, TeamSpeak and any other game ive tried them with, but for some reason it wont with CSGO.

When i go to my audio options and then the Mic Setup from the CSGO menues it just brings me to the Steam mic settings, inside there how ever it is showing my microphone constantly registering noise (the sound metere that shows you when your talking) and never fluctuates. Ive tried to switch my audio device that my Steam is using, but it wont alow me to so that seems to be out.

I have a SoundBlaster Z audio card, if anyone has used this headset (PX4) with a soundblaster z card any tips or pointers would be appreciated.
