Alright, so I have the Maximus VI Hero, and since I purchased it in September, I have had an issue with the rear audio panel. I have a pair of Turtle Beach DX12's. These headphones have two options for connection. First, via the green (audio) and pink (mic) RCA plugs, and second via Optical Toslink and USB (this is used for the Dolby Digital 5.1 Surround sound for Xbox 360). The problem I'm having is this: When I connect my green/pink RCA's to the front panel, Realteks HD Sound Manager automatically detects them. Once assigned, I can go into the HD Audio Manager and select Stereo, Quad, 5.1, or 7.1. I use 5.1 and it works without a hitch. However I would like to have this headset plugged into the back panel, and when I do so (same connection with green/pink RCA) it recognizes that I have plugged them in, but 5.1 is not available from the dropdown menu. I updated the HD Audio Manager via Asus Support and Download, and then 5.1 became available in the dropdown menu, but no sound is played when you test the center/surround outputs. I then went to Realteks website and updated the audio driver. That is where I'm at now, and now when I test the output for center channel, it plays bass only, and still basically is not functioning properly. Front panel still works fine though. :mad: What am I missing or what have I done wrong??? Thanks for your help!
