Just replaced my TV and TV speaker. SONY Bravia and Bose 900 Sound bar.
I am currently running HDMI from Roku to Bravia OEC HDMI port;.Optical cable from Bravia to Bose 900.
Is there a way to control power of TV and speaker with the Roku remote?
Would also like to control Bose volume with the Roku remote. Any tips?
There have been many threads over the years with this or a similar question and I think it's safe to say the answer is "no". Just search the "community" for Bose. Unless you can connect the soundbar to the TV via HDMI-ARC and use CEC (or Bravia-sync, I think Sony calls it) there's no way to configure a Roku remote to control anything other than a TV.
