I've got the two 4850s, in crossfire mode. I have my monitor connected to the main 4850 via DVI. I also have my AV receiver connected to the main 4850 via HDMI (for audio only) But my PC keeps on thinking that I'm attempting to run two monitors simultaneously. ATI's drivers picks up my AV receiver as a second monitor which is wrong I just want the audio only. If I disable HDMI display in ATI's drivers I also loose the audio outputs too. Also, I have a headset (microphone and speakers), they use 3.5mm jacks (pink + green) how do I go about connecting them up using the 4850. Is there any way I can connect the 4850 to the front panel audio on my cause. Thanks again.
