People i really need to know if there is anyone with the same issue as me. I still have time to return the Soundcard.
Please let me know if you Xonar owners can hear a static noise coming trhough your headphones or not, when you pause a video.
1. Set Xonar driver to 8 channel mode
2. Open a random video (youtube f.e.)
3. Pause it
4. Set Maximum Volume to hear a possible noise.
If anyone can hear it let me know, so ill return the card immediately. otherwise ill check for a solution.
