Evidently, this is a common problem. I'm not getting 5.1 sound, or ANY sound when the source is 5.1 from the optical out into my Sonos soundbar (I have a full 5.1 sonos setup). The complete setup is as follows: Samsung TV Nintendo connected via component Cable box HDMI Roku 3 HDMI. Optical audio out into Sonos playbar I tried every parameter I can think of, set everything I see to DD, no good. I cant get netflix or anything else to play in 5.1, only stereo. I'm under the inpression a device like this one can solve my problem, to keep the audio from ever getting to the TV and just pass video to it? For only $39.15 each when QTY 50+ purchased - 4X1 HDMI® Switcher w/ Toslink & Digital Coaxial Port (Rev.2) w/ 3D support. Thank you in advance.
