Well, that's was I was thinking too... Sadly I can not get it to work yet.
Put dongle in Desktop, works like a champ.
Plugged into Surface, NO Sound. I checked the Playback devices and made it default. The Volume bar is fluctuating as it is receiving sounds....
I am Sure if I call Logitech they will say, it works in your computers, our stuff is fine. So, Where will MS Stand on this.
All that Said.... I love my Surface and they can not have it back......
