I just swapped out one Bolt for another through Tivo's replacement program and now I can't get the new remote to control the sound bar. I've been round and round with Tivo support, both chat and on the phone and they've given up and passed the buck to Vizio...insisting I should call Vizio and get a new programming code! Here's the configuration: Vizio 70" TV (D70-F3) and an older Vizio Sound Bar (VHT215) connected with optical cable. Tivo Bolt with Spectrum cable card and newer IR/RF remote. The Tivo settings menu says use code 1180 for AV control but I've tried that and a host of others. All I know is the previous remote worked fine but what I don't know is actually how things were set up. Was the Tivo remote controlling the TV and the sound bar independently or was it controlling the TV which was passing the commands to the Sound Bar? Would it matter which TV code I entered into the Tivo for control of the TV for it to do that? I just realized I recently changed TVs and made no changes to the Tivo remote so that rules out that the TV is controlling the sound bar. I realize the TV can control the sound bar if connected with analog cables but it's always been optical and not sure I want to give up on that. One Tivo support person seemed to believe the problem was that the sound bar needed to be connected to the Bolt, not the TV! I've tried it both ways with no difference although I can't say I tried every possible programming code while the sound bar was connected to the Bolt. I've also tried scanning possible codes by entering the 1999 code after pressing and holding the Tivo and the mute buttons until I got the red programming light, then pressing channel up every two seconds for forever! I gave up after about 30 attempts. Any ideas?
