Hey Stephan, Yup, I've tried passing both 3/0/0 and 3/0/1 and no go, and I also make sure to reboot the host in between runs due to the amd hardware issue. I don't believe 3/0/1 is necessary though based on the examples by Corvin in his talk. He only passed in 3/0/0 (I'm guessing his card also has a 3/0/1 function that he isn't using since that's the audio channel).
