Ok this has been driving me bonkers since launch. My setup is as follows
Virgin tivo into xbox one into Sony str dg820 av amp into telly, all connected via HDMI.
I have tried every setting combo I can think of and am still only able to get stereo when watching tv. Sound on the xbox is fine and I can have it in 5.1 or DTS and it all works but as soon as I put the tv on it just outputs it in stereo and my amp won't allow me to mix it into any other speakers. I've tried the surround beta but it makes no difference I even have the new beta update and still no joy.
Has anyone else encountered this problem with virgin TiVo or am I just being stupid. Any help would be appreciated.
