I’ve basically never had luck with DVDAudioExtractor and Blu rays.My copy arrived yesterday. I'm not having success using DVDAudioExtractor to create files with more than 2 channels. Anyone else?
My flow these days is to rip the file with the surround mix using MakeMKV, which turns the whole multichannel mix into a single file with the visuals and audio, and then use @HomerJAU’s fantastic Music Media Helper to split and tag that single .mkv file into either multichannel flac or Atmos mkvs.
If you rip all the audio tracks at once you can run it through Music Media Helper multiple times and choose the track you want to use.
