There is no "sloppy implementation" in Windows.
Windows has the mandatory Bluetooth baseline implementation.
Other mobile device manufacturers paid extra money on optional higher quality Bluetooth audio codecs.
It is up to your laptop manufacturer to pay extra money to Intel (which makes the Bluetooth chip) and then Intel pays the appropriate licensing fee to the the appropriate patent holders to those optional higher quality Bluetooth audio codecs.
It is a money issue, so no feedback is ever going to solve your problem.
Is there a way to know what device supports these "higher quality Bluetooth audio codecs", or are we left with buying and being lucky? Or it will never work with Windows at all because of the "mandatory Bluetooth baseline implementation"? Is it a hardware or a software problem after all?
I paid extra money specifically on a Bluetooth motherboard and you're telling us (from what I understood) the fault is with the hardware manufacturers, so... That's bad.
