I have a gigabyte gt710 graphics card, that is connect through a hdmi to dvi cable to a dvi screen. I want to use the audio and mic ports on the front of my case but when I plug a headset in nothing comes up on the "audio" tab in control panel and I cannot select my headset in volume mixer. Of course there is no audio coming out of my dvi monitor but it works in my hdmi tv. If anyone has any clue what I'm talking about, could you please explain what I have to do (any external links are accepted) to get my headset (plugged into the headphone jacks) to work. Thanks in advance. Angus...
