RC122 Remote will not operate Vizio Sound Bar model: SB2920-C6
I followed the directions http://www.timewarnercable.com/content/twc/en/support/program-your-remote/RC122.html
with tech on the phone.
Also did the 991 scan option 4 times.
Called Vizio tech support, they reffered back to Time Warner Cable.
Called Philips tect support, they said they have been having problems since 2012 with adding audio devices to the AUX button.
