Default [Q] blutooth headset not working cyanogenmod 6.1.2

i've just flashed the latest version of cyanogenmod 6.1.2 (android 2.2) to my gt540 and my bluetooth headset isn't working, i can control the phone through it i.e hang up, the call isn't going through my phone but there is only a slight buzzing sound through the headset and also my phone still is able to stream music through bluetooth.

i was wondering if there is anything i can do to re-enable bluetooth?
maybe a third party call app?

because i really like the rom i think it's amazing and i don't really want to go back to 2.1 or 1.6
