This code worked for me 32454. I have a new box and the XR-11 voice remote. I followed the on screen directions for the TV and sound bar pairing, and then used this code for my vizio sound bar: 32454. You may have to sync the tv and sound bar power buttons by turning one or both off, as well as the cable box. Use the "all power" button to to everything on. The cable box will not shut off as it is designed that way. You can go into your settings for the cable box and select the power saver mode. I have mine set to the lowest setting which is 1 hour, and then it will sleep, or at least it should...

Hope this helps
