I cannot get sound from my MM 100 Sennheiser stereo headset. It pairs and connects but does not show in sound-playback tab. Sony laptop VGN AW-290j. I reinstalled the Bluetooth drivers from sony but no go.
Please post an image of your Device Manager.
Have your headset connected to the PC when you create the image.
Get updated drivers for your bluetooth card. Don't rely on Sony drivers.
I had the same issue, then i downloaded driver from intel website for my N1030 and it resolved. While with official Dell driver , there were 3 "Peripheral Bluetooth Devices" showing in Device Manager.
