I honestly don't remember if this was an issue in win 7 or not, I'm not too convinced it was though. the driver page on the avid site only says support up to windows 8.1, nothing on 10, but that shouldn't matter right?
Anyway, Sony vegas screwed up the render a bit, the point is that in the second clip the audio is "Supposed" to be fine, just a issue on my part with the render settings. The first clip however, came out exactly as I hear it on my computer.
