I've had a Marantz 7011 for a couple of years now. Bluetooth has always been iffy - I often have had to unpair and re-pair both my HP laptop and my Surface 7 to get it to play. As of a couple of days I can't get it to play bluetooth audio from anything. My Surface says that it's paired, it shows up on the Marantz display, but sound still come out of the Surface speakers. Same with an old Windows Phone I had lying around. Both devices show as paired, sound come out of the phone. When I tried to pair my Galaxy 10 to compare, it won't even connect at all. It shows up on the Marantz display, but the Galaxy gives me the "unable to pair" message. At first I assumed it was the Surface having the issue, but now it seems like it must be the Marantz.
