I had a problem too when creating a blu-ray iso file with a blu-ray title ripped in mkv passthrough mode, I have no sound in the iso create file when the ripped file works fine (DTS HD HR Audio).
As for this problem of no sound in the created iso file,
1. Please attach the related dvdfab_internal.log and fabcheck_internal.log as attachment here.
2. Mount the iso file using DVDFab Virtual Drive, open it in File Explorer, locate the largest m2ts file, and then use MediaInfo tool to analyze and post the result.
3. Is there other audio track except the DTS HD HR Audio? Please try to switch to other audio track to play again?
