I'm running Windows 7 64-bit with an Asus P8P67 Mobo. I have a 5.1 surround sound system plugged into the optical out on my mobo I/O. I however can't seem to get 5.1 audio even with 5.1 encoded media etc. Using the latest Realtek HD Audio drivers as well but no option to set as 5.1.
Would really appreciate some help. Let me know if you need more system info.
