Cheers

of course it records broken static noise, because ac-3 data is not audio
if you wish to record it as-is (in 'binary' form), turn on 'direct spdif recording' -- you will get the data unmodified
note that you will need to convert the recorded 'noise' into a valid ac-3 stream by using some utilities

if you wish to record the ac-3 data as 'sound', turn on 'spdif-in ac-3 decoding' option and record 'what you hear'

If you are doing direct digital recording, you can play PCM wave files directly, but AC3 wave files most likely need to be fixed with BeSplit

example command line:

BeSplit -core( -input wave1.wav -prefix c:\ -type ddwav -fix )

see DSPguru's example #6:
