just picked up a sound bar (samsung curved hw-jm4000c 4 series) to use with samsung curved tv (2015 model?) both from costco. wanted to get both power and vol working on the bolt remote and typical setup following the tivo suggestion screens got me tivo working volume but not power, i.e tivo turned off tv, but not a/v so sound continued. to get the arc working via the bolt remote, use the arc hdmi input on the tv, and use the a/v vol + mute control code (1304 iirc) for the power + vol/mute setup. 1304 is on the a/v screen of codes, but not on the power screen and that probably makes sense due to arc. 1304 also allows for press and hold vol change. hope that helps someone else out.
