Not an expert on any of this so please go easy.
I bought a new LG CX, which is outputting to my beam via hdmi. I also have a pair of Play 1s as rears, and sub. Everything works great from the internal TV apps and via Sky Q
This issue I have is with my PC, which is connected to the TV via hdmi. I'm trying to get it to output Dolby 5.1 but because it knows it's connected to a TV it won't. I don't think there's a way around for this without messing about with new sound card/optical cables or connecting straight to the beam from the PC - unless anyone knows different?
However, the PC can output atmos (I've installed the codec) and as the CX can down-convert that to Dolby digital for the beam (as I understand it) I figured I could do that. When I try, the Sonos app reports that it's receiving a Dolby 5.1 signal, but I still get nothing from the rear speakers. What am I missing?
Any help appreciated. Spent a fortune on the PC and it's annoying only to get stereo out of it..
