Ask and ye shall receive. Here are a couple publicly available files that demonstrate what appear to be two different problems with sndarray in the blessed Pygame example.
WAV http://www.freesound.org/samplesViewSingle.php?id=4359 blows up on line 88, "ValueError: shape mismatch: objects cannot be broadcast to a single shape". This one kinda surprised me. OGG http://www.freesound.org/samplesViewSingle.php?id=32083 blows up on line 108, "ValueError: buffer size must be a multiple of element size".
