Sonos ARC with Samsung 60f8500 plasma only stereo
Hi there. My Arc is connected to the HMDI ARC on my tv, but no matter hwat i’ve tried i cannot get it to output 5.1. Netflix/prime/tv etc. Sound works fine but the app keeps saying its playing in stereo. I have tried using the optical adapter as well - same issue. the DD option in the TV menu is greyed out and “PCM” is the only option I can use. I’ve even tried using an hdmi switcher which changed nothing. TV and Arc and the app are all on their latest software version. Tried multiple HDMI cables, sources, etc. Thoughts?
