Dolby Digital Optical cable
When I play a game from steam my speaker's receiver say "Pro Logic movie" which as far as I know isn't true 5.1. I know my motherboard is capable of 5.1 digital as I can test it in control panel and the digital test works just fine. Also when I have them hooked up in the same format (ie. same cable same speakers)to my playstation I get dolby 5.1
Hopefully someone can help me with this. I'm also using the Realtek hd audio Manager.
Not sure if this is the correct section. Let me know if you need anymore info.
I noticed this too I have a newer Asus mobo. It happened all of the sudden like a windows update hit and I lost dolby digital 5.1. I game with my pc all of the time and have it hooked up to my ht receiver.
