You could use Sox or Audacity for example.

Although AIF files are big-endian, did you try to use the "l" flag 
nevertheless?

Try as well: Converting the 24bit aif file to a 4Chn wav file (Sox) and 
try that one. Convert the 24bit aif file to 16bits and try again. Make 
sure to report back to the list with your results!
