JP1 Remotes

The Comcast X1 remote (version U2) does not have a plug in the battery compartment. I get the feeling that buying a universal remote is my only option. Looking for a recommendation for one that has RC (for hidden Xfinity STB) and IR for TV and soundbar. Thanks

Is it possible to program the Xfinity X! remote (version U2) to control a Samsung Soundbar (model HW-H550)? Comcast does not publish any codes for soundbar audio devices? Looking for a 5-diget code but am willing to learn how to program manually, if I know it can be done.

Thanks for you help - I am ...
