Try with the last drivers from my thread : [DRIVERS] AMD|MediaTek WiFi/Bluetooth
i had a problem with my bluetooth. it wasnt pairing on any devices. so what i done was(sorry bad english).
clean install windows ( i didnt installed armoury crate via motherboard "thing")
then update windows with all available updates what there is.
THEN: i downloaded Armoury crate (but dont install ALL drivers at once)
install chipset driver, restart pc
install LAN driver, restart pc
install bluetooth driver, restart pc, then try to pair device to check if it works
install wifi driver,restart pc
install audio driver,restart pc
this was the ONLY way i got my bluetooth working
