I just enabled the onboard Bluetooth on my Z68 board to see how Windows 8 reacts. I will go through the process in case you might have had a different experience. If you do not know, the Device Manager can be opened by Winkey+X and selecting it on the menu. This is where I am checking for the devices I mention.
First, I see no Bluetooth Windows 8 drivers on the ASUS site. So I have to assume they are built into Windows 8, or can be downloaded. When the system started there were no Bluetooth entries in the Device Manager, but the the system started to load the drivers automatically. When it was done, I had a Bluetooth entry with
ASUS Bluetooth and
Microsoft Bluetooth Enumerator.
Also two Network devices were added in the Network Adapters section, and in the Other Devices section, a
Bluetooth Peripheral Device with a question mark.
I have now added a Bluetooth mouse which seems to be working fine. Nothing changed under the Other Devices, but it was added under Bluetooth. The mouse does not require a pairing number, so it paired with little effort.
Speakers or a headset might be set up differently and be more complicated, but I do not have any to test. If you would let me know what model the speakers are, I will see if I can find anything, but do you know if they have their own drivers? Are they showing up under the Bluetooth or Sound,Video and Game Controllers sections in Device Manager?
Do you know the manufacturer of the drivers for the Bluetooth on the Samsung. I think the ASUS ones are related to Atheros on this board.
My next quest will be to find out why the Other devices are showing with Question Marks...
