I've just bought and set up a new Samsung UA55F8000AM television, along with a Sonos Playbar, Sub and 2x Play:1 for a home theatre set up. The set up has gone relatively well, however I'm having trouble controlling the volume correctly. I've tried to disable the TV speakers, however when I change the TV speaker settings to "External Speakers" the remote no longer controls volume, and an error message is displayed on the screen saying to control the volume on the external speakers. If I reactivate the TV speaker, the TV volume is controlled by the remote, however the Playbar does not change volume with the TV - instead, the Playbar volume must be controlled via the Sonos App on my iPhone. Can I reset the Playbar and attempt to set it up correctly? Please help!!
