Missing audio on ProRes 32 bit float, and 24 bit pcm
#9
I have now duplicated the missing audio in a second long capture as interlaced to be de-interlaced.  I captured a video that is 2hrs 23 minutes long and after checking it carefully, the deinterlacing is good but the audio is missing.  I have divided the file in half, and both of the halves complete just fine.  This is definitely a problem with a PreRes file and Hybrid.  I have uploaded the second file to my dropbox for you to take a look at.  I also loaded the two halves that DO De-interlace with Audio using Hybrid.  The Larger file doesn't and here is the MediaInfo output of that file.

I hope you are able to see this problem with these files.
