I only get sound from the front left and right speakers. I have 64 bit Windows 7 and Realtek HD audio with updated drivers. I run the hdmi through the video card(AMD Radeon HD 6800 Series) to my receiver. When I go into the configuration for Realtek and test the speakers individually, they all work. My Receiver always says decoder off. What can I do to get surround coming from my pc? It seems like a lot of people have problems with this and answers likewise seem difficult to come by. Thank you.
You shouldnt be using the Realtek HD audio, that is for the on-board audio of the motherboard. You need to use the AMD HDMI audio, make sure the drivers are loaded for that, and it is selected as your default audio device.
Well, I technically have to just to hear any audio. Well I just changed a setting, so let me get a 5.1 source to see if it changed. By the way, I'm assuming youtube is not a 5.1 source even if it is a 5.1 audio test video?
