Roku Soundbar not transmitting audio to TV via HDMI

I just purchased a roku soundbar and connected it to my samsung 8 series uhd tv using the provided hdmi arc cable. My tv is connected to my home theatre system using optical out on my tv. The problem is that roku soundbar doesn't transfer sound via hdmi to my tv so there's no way to use my soundbar to feed audio to my home theatre system.
