Hi @JONATHAN_MG,
The engineering team has reviewed the FLAC files you shared. This seems to be a specific error with these files, as we can play other FLAC files fine in 5.1.7.
They do play fine for e.g. in QuickTime Player, but not with CoreAudio directly (using AU Lab). Our guess is they are corrupt in some way. Can you please confirm if these files from the same source / encoder? Thanks!
