I have this computer wired through the S/PDIF Digital Coax output into my Onkyo 7.1 Surround receiver. I am trying to get 5.1/7.1 for streaming movies (Prime/Netflix). When I try to set up Speaker configuration 2 speaker stereo is the only option available in Windows Sound, When I go to Realtek Audio Manager again 2 speaker stereo is my only option. I have tried the Troubleshooter, HP Support tool, and installing latest driver from Realtek for Integrated Realtek ALC888S.
I also tried wiring through HDMI and get the same result, but I think that is because I daisy-chained it through the TV (HDMI into TV, TV Toslink out to Receiver). Nothing helps. It has a GE Force G210 Graphics card.
Any thoughts?
