I have been experiencing this problem for weeks, and I cannot seem to find a solution anywhere. Every time I want to record audio directly onto Sony VEGAS Pro 17, I click the record button (bottom left) and it creates a whole new audio track. It disregards that I set audio track 1 as my recording track. And, on top of that, it does not even record in the new track. So I am left with two empty audio tracks. There is no audio file at all. Not even a silent one. It just refuses to record.
