USB bluetooth issue

[11mrtom]

So when I connect my “I Tech” USB bluetooth adapter (V 2.0)to my Acer 8.1, device detected and drivers load. I change the bluetooth surport service to automatic & manage to pair my Anker bluetooth speakers with the laptop. However, when I power on the speakers, sound drops from the laptop and the Anker speakers work for a moment then nothing. I have the Anker inches away from the USB bluetooth device. The speakers work fine with my Android phone. Task manager reports Bluetooth not connected.
Thoughts welcome..
