The following information is available in the Help section of the Bluetooth* driver, under Product Description:
Advanced Audio Distribution Profile (A2DP) (Source/Sink): Windows 8 and Windows 8.1 support audio profiles natively. In turn, interaction with media players and VoIP software is out of scope for Intel® PROSet/Wireless Software for Bluetooth® Technology from Windows 8 onwards.
I suggest contacting Microsoft* in regards of this inquiry.
I apologize for the inconvenience.
