I've searched long and far, but can't seem to find anyone with the same issue. Looking for ideas to see if there is anything obvious I'm missing. Using a Playbar & 2x Play 3's.
Current set-up is:
HTPC (Windows 10 / nvidia GTX 960 HDMI Output for Audio and Video) - > Monoprice HDMI Switch - > Playbar (VIA Optical)
I've set Kodi to Passthrough and I get 5.1 for anything that plays though Kodi, verified through About My Sonos System.
Anytime I play Video or a Game through Windows though it is only pushing out Stereo, again verified through About My Sonos System. I've set the internal Speaker Set-up in windows to 5.1 and even tried stereo, but still only stereo is being sent out. Windows test only plays on left and right channel.
I've verified all content is AAC that I have been testing this with, and been at this for about two weeks trying to figure out whats going on here.
Any other thoughts?
