Audio [Q] Bluetooth headset not showing up

I've already connected different bluetooth things to my TF201 (with CM, so it's 4.3.1), but am not able to connect my bluetooth headset to it. The tablet just doesn't see the device. (I already had this problem before I installed CM). Is there something I could change in order to make it visible to the tablet. Most peoples issues around this is that they don't pair when the device is visible, my headset is just not showing up (I assume that it is not related to the CM)

Kind regards
