Comment (by therentabrain):

 I was looking to see if my problem is the same as this problem and I tried
 playing your sample file.  I'm using Windows 10 which maybe doesn't work
 with CAF files, but I thought I would report what happened.

 Winamp plays it as noise, and decoding it with Monkey's Audio results in a
 WAV that plays the same.

 Interestingly, Monkey's Audio says it verifies OK.

 The info it shows:
 I:\24_bit_fixed_caf.ape
 Monkey's Audio 3.99 (Normal)
 Format: 48.0 khz, 24 bit, 2 ch
 Length: 0:06 (324266 blocks)
 Tag: None (0 bytes)

 I came here to report that a file of mine was partially turned to
 seemingly the same kind of noise when decoding from ape to wav.  After a
 bunch of noise blasts, the rest of the file plays fine.

 My file's info:
 I:\two ring circus.WAS.ape
 Monkey's Audio 3.88 (Extra High)
 Format: 44.1 khz, 16 bit, 2 ch
 Length: 5:54 (15625750 blocks)
 Tag: None (0 bytes)
