Had a cloud II headset that was being complicated, and the 5.1 sound wasn't working. I had to enable the type of sound my headset was supposed to be in the asus xonar settings for the card to adjust to my headset properly.
Gets the job done; Interface that helps with a lot of sound problems
Doesn't sit in the PCI slot efficiently; If I plug anything into the audio or mic ports directly, the card moves out of the slot; Will not work when I screw in the card; I have to sit it diagonal in the PCI, and leave it alone; 2 weeks so far without touching it and I have had no problems
