Roamio Basic and Vizio Soundbar

I have a Vizio HDTV that controls the volume of my Vizio sound bar. Works good.



In order to turn on the sound bar with the TV I had to use my learning remote and sound bar remote and marry them.



Now my learning remote will turn on my TV and sound bar. It will also turn both off. Works good.



Monday I will be receiving my new Roamio Basic and I'll want to use the Roamio RF remote for my TV, DVR and sound bar.



I've found instructions for using the Roamio RF remote to program it to turn on and off my TV so I can use the RF and IR features of the remote.



My question/issue is: How do I use my new Roamio RF/IR remote to also turn on my sound bar???



I hope my question is not redundant but I searched the Internet and could not find an easy to understand answer.



If the Roamio RF/IR remote has the learning feature I can marry my sound bar and remote the same way I did with my Glo Backlight remote.



Thanks.
