I am trying to link my Vizio SB3621N-E8M Sound Bar to my RC122 remote's AUX button. I have tried manually linking them with the 3479 code and the 4 other codes that Vizio has on their site but none have worked. I have also tied linking them via the auto search method and that has not worked either. I have the sound bar connected to the tv using an optical cable. Any help would be most appreciated. Thank you.
I liked a friend's RC122 AUX to a Sony audio anp using Auto Code and it took a LONG TIME to pick up the code (about 3 min). Patience was rewarded.
If the soundbar has HDMI in and the TV has an HDMI ARC port, use that instead. The TV's volume will control the sound bar volume.
