I'm setting up Roku streaming stick +. My sound bar is connected HDMI to my TV, The Roku remote will not turn on sound bar with TV yet it will turn it off?
Roku remotes only control tv's, no audio devices. Its upto the tv to control the audio gear via hdmi-cec. So your tv is not completely off its in a state to accept an IR command to power it on, but it may not be in a state to also send a command to third device like your sound bar? Once already on, it can turn off the sound bar as it is put in to standby.
Try refreshing the HDMI devices in the tv menu.
Unsuccessful, thanks though

I got mine working.
I connected my RokuStick+ into the hdmi input of my sound bar and then hdmi from output of sound bar connected to TV. You may need to enable ARC in your TV settings, My Sony tv was older so the setting was HDMI control. Same thing. Now I can use the Roku remote to turn on the tv, turn off sound bar and tv simultaneously and the volume controls control sound bar volume.
Note: the stick wouldn’t fit to plug into input of my sound bar. I had to order the free extender from the website. Came pretty quickly.
