.aiff files won't play in finder (and some programs)
Mac Pro 4.1
Doing some long-overdue file cleanup, and when I preview some .aiff files in the finder they won't play. The Apple .aiff sound effect files play, but things I've recorded won't play, although they will play if imported into iTunes. Other audio formats are playing fine in Finder.
Also, a recording program I sometimes use called Tracktion will play files in other formats, but my .aiff files are silent or pure harsh static.
Is there a global setting that might be corrupted somewhere? Could this be the fault of my recent Mavericks installation?
Thanks!
Mac Pro, OS X Mavericks (10.9.1), 4.1
