Sharp Roku TV LC-50LBU711U - Sony AV System STR-KS360
Connected Optical Output from TV to Optical Input on AV system only displays R, L & Subwoofer.
I was hoping to get 5.1 audio, since I'm watching 5.1 movies.
My AV System doesn't have an ARC input.
Playing Blu-Rays from my Player to AV System provides 5.1 audio via HDMI, so I know it works.
Am I missing something?
