Just purchased the Creative wp-450 headset and the Creative BT-D1 USB audio transmitter because my computer has no bluetooth. I paired the headset to the USB transmitter, it is showing up under the playback tab in audio devices and can play audio. The problem is it is not showing up under the recording tab and the mic is not being recognized. The instructions say that to utilize the mic you need to connect the headset as a hands-free audio device or headset device instead of a stereo audio device but I have not been able to figure out how to do this. I've set the headset as the default audio and communication device, the recording tab is set to show disabled and disconnected devices and it doesn't seem to be an issue with any bluetooth settings because the headset is paired to the transmitter, not the computer itself. Any ideas?
