Thanks, Michael. I noticed Koz said that right-click > " Open with" 
imports all files fine on that machine with the problem.

Actually, it's a fairly consistent theme with the history of flaky PCM
import that right-click > Open with (or drag) is more likely to succeed.
When I couldn't always reproduce that problem we had where 16-bit
WAV/AIFF imported as noise into 24-bit projects set to "copy in", 
it was often right-click or drag that made the import work, whereas
using File > Open or File > Import failed.
