Bluetooth headset pairs but NO AUDIO

Hi,

My Laptop (Dell Latitude E5410) is pairing Bluetooth headset (Chorus WP-350)  just fine. But I can't choose any bluetooth audio from "Sound and Audio Device proterties".  I can see only "IDT Audio" as Default device even the BT audio gateway is on. So NO SOUND. I have updated latest BT and Audio drivers without any help.
