Hello All;I'm new to the forum and have a basic understanding of both software and hardware. I have two Dell Studio laptops(PC replacement style) a 1747 and 1749 both running Windows 7 Home Premium with service pack 1. I recently added several bluetooth combination stereo headphone/microphone communication devices. Both were recognized and paired with no problem. However, one computer wouldn't show the "advanced features" . It loaded just the headset driver not the audio device driver. To recap, one computer allows the bluetooth devices to be used for communication and as a stereo headset while the other allows the devices to be used for communication only. Any thoughts?
