Razer Kraken TE Game/Chat adjuster not working

Hi I have just got myself a Razer Kraken Tournament Edition, Sound quality is good with THX Spatial audio however the game/chat adjuster doesn't work at all, If I turn the adjuster to focus more on chat than game, it just quietens all audio to basically mute INCLUDING the chat and if I do it the other way, where I adjust it to game audio, it makes everything louder including chat, basicallty making the adjuster a volume up/down wheel rather than what it is meant to do, I have set the chat and game headset as my default device and default communications device, but it doesnt seem to change anything. Has anyone else had the same issue?
