I have a 2013 Samsung 55” FH6003 LED TV that does not support CEC nor have an optical port. I want to integrate the Sonos Beam with the TV and build a surround sound. I have a Roku Ultra as the service provider. I have added a KanexPro HDMI Audio Extractor between the Rodu Ultra and the TV. Video out of KanexPro to TV is great via HDMI. But I do not seem to be getting the audio from the KanexPro to the Sonos Beam via optical cable. When I try to connect the beam to the TV (which is actually direct to the Roku Ultra through the Kanex Pro) the app does not read the signal. Any help, ideas or comments would be greatly appreciated.
