I see it's been several months since you posted, so I assume you've figured it out by now, but in case you haven't (or if there's anyone else as frustrated with this as I was), thought I'd post the steps necessary. We have a Sony tv and a Bose sound bar which is connected w/ an optical cable. The process seems to be to first pair your tv, then stop and exit the programming. After that, do not go through the "settings" route to program the soundbar. Instead, just press the Xfinity + mute buttons on their own, then enter the Soundbar code. Here are the steps I followed to success: 1 - pair your XR15 remote with your tv as instructed. When it asks if you can control volume, try the volume buttons and although you won't be able to control the volume, if you get the "tv audio is fixed" error message, that means it's trying and is paired to the tv screen. Just say "yes" and exit. 2 - Exit completely out of programming and settings and just tune to a normal channel. 3 - With the tv and sound bar on, do not select settings. Instead, just press the Xfinity + mute buttons together for about 5 sec until the remote light turns green. 4 - You won't see any prompts on the screen. In fact, the screen does not display anything to indicate any programming is going on. Just enter the 31933 Bose code. 5 - The remote light will flash green. Try using the volume buttons, and hopefully you will be as surprised as I was that it now works. Very, very silly that Comcast does not have these instructions anywhere - - - at least anywhere I could find. I was just so frustrated that I tried anything and got lucky.
