I get the ever useful "Unknown error" when exporting the audio from Premiere Pro CS6 to a 32-bit, 5.1 channel uncompressed WAV file most of the time. I was able to get it to work just fine by pasting the audio to a new project, but that isn't working anymore. I get the same error when I change it to 24-bit audio. However, when I change to 16-bit sound it works fine.
First, is there a real audible difference between 16- and 32-bit when it's all going through a WAV to AC3 converter? The AC3 files get dumped into Encore as the audio track so that I can get 5.1 sound on blu-rays instead of Encore re-encoding things.
Second, what would cause it suddenly not work, and how can I get it working again?
