My Sony Bravia TV and Sonos Playbar are next to each other. My standard IR remote that came with my TV triggers the volume on my TV (it's fixed), but doesn't change the volume on my player - unless I get up close to the playbar and point the remote directly at the playbar instead of the TV sensor. Do I need to purchase a separate remote for the volume of the player? I'd rather keep it to one remote. Why does the IR information not come across the optical audio cable? Could I fix this by doing an ethernet cable from my TV to playbar? I've repaired my remote a few times and it works for a minute or so, then goes back to not working. Any advice?
