My Asus Z87-a motherboard with Windows 8.1 Pro will not output to the side or rear speakers of my 7.1 surround setup. I am using the 6 rear analogue connectors but the only ones not working is the side speaker out and rear speaker out. Front and Subwoofer work fine (after re-installing the audio drivers).
Does anyone know how to fix this?
