Nope, using the Dolby app. I also tried turning Dolby off to see if that fixed the issue, changed the shared sample rate, speaker config, etc...the newest driver will not work no matter what settings I use. The first Windows 8 one seemed to work ok in 2 channel, but the internal audio on the Maximus V Formula is so inferior I can't stand using it so I'm dealing with no Netflix/Hulu apps until a fix is provided. I will (hopefully on Sunday) take a Youtube video of the issue to hopefully make it go viral and force a fix. I've complained about this since the start of drivers for Windows 8, I had since went back to 7, but now reinstalled 8 UEFI (which is fantastic, btw) and don't feel this issue should still be around.
Also by complained, yes, I mean I submitted a proper bug report to the "Xonar team".
