So, I've done some searching and found some topics from people with similar problems, but I haven't found exactly what I was looking for so I'll give it a shot here. I'm running sound from my 570 GTX to an RCA 5.1 sound receiver (a pretty cheap reciever I know, and that may end up being my problem) via an HDMI cable which is connected to my tv via another HDMI cable. The problem is when I go to set up the speakers through windows sound setting, I only have the option for stereo sound. I have the newest driver which includes the HDMI audio driver. Stereo sound works fine, but I'd like to be able to have 5 channel sound. Thanks in advance for any help you may have.
