MacBook Pro MV912LL/A Bluetooth sound issues windows 10

I just purchased a new MacBook Pro MV912LL/A. I installed windows 10 using bootcamp and I paired a bluetooth soundbar but I am noticing it cuts off every 20-25 seconds where as it works fine with other windows laptops. It even works fine when I boot into Mac partition.

  • Can you disable the 'Allow the computer to turn off this device to save power' for the 802.11ac adapter?
  • On the macOS side, run BC Assistant -> Action -> Download and check the version of driver provided by BC for the 802.11ac adapter in the Bootcamp.xml file?

As soon as I disabled my network adapter (i.e. unchecked 'Allow the computer to turn off this device to save power') it shows connected but internet doesn't seem to work. I had to turn Airplane Mode to 'On' and turn it back to 'Off' to get my internet back functioning. It seems to be working so thanks for all your help. Though I am surprised why would it work. Here is what it shows in BootCamp.xml which is the same as in Windows Device Manager.
