HI... I have an HDMI cable from my Fios box into a Sony Bravia TV. I have an HDMI Cable from the HDMI ARC into the Streambar. When I launch Roku the sound comes out of the soundbar just fine. When I change input to FIOS I hear sound through the sound bar until I change the channel. When I change channel the sound doesn't work any longer I have to change the audio setting on the Sony from Audio System to TV Speaker and can't hear anything out of the soundbar. I thought I'd be able to use the sound bar full-time. Thoughts? thank you!
