I've got a set of PC350's plugged into an ASUS Xonar DGX and an HT Omega Claro (microphone sounds like garbage on the Claro), and Dolby Headphone/7.1 Virtual Speaker options in the Claro driver audio center doesn't seem to function anymore. I'm just getting flat, bad audio as if the headset were just plugged into the motherboard. Any help?

Does Windows work properly with dual sound cards? I didn't realize it did. I thought it was only possible to configure one sound device as the default output device. Did you research first to find out if Windows will indeed support that?

Have you disabled the motherboard's on-board audio? in the BIOS
Maybe remove the Omega Claro and just use the DGX?

Looks like it is possible to have two soundcards :http://www.head-fi.org/t/518081/two-sound-cards-in-windows-7
