I've been using FCP for a long time but I have never ran into this issue.
I am trying to capture HDV footage. The audio is selected to be captured. It plays back through the capture tool but at the same time when I look at the meters they don't show any audio at all. Everything is selected as it should be, I have tried using capture now and the audio does come through that way. I have trashed the preferences but still it won't capture audio on batch.
