I am experiencing some problems with the sound from my ps4 and I am wondering if anyone else has found a solution. So I was using my ps3 via optical just fine, both movies and games would utilise 5.1 just fine. However I put the optical cable in my ps4 and its a different story. Firstly it plays sound though the optical and hdmi at the same time which is annoying, secondly it doesent produce 5.1 It seems to be 2.1. Has anyone else had this issue? Thanks.
