I suspect that 13K may be too small to exhibit the problem -
specifically, it may be within the probe limit. Where the data was
zeroed from may also make a difference; did you zero data starting at
the very beginning of the file?

Nope - with the initial 100k of zero data removed, the file is presently
playing just fine, and is nearly 15 minutes in already. Whether or not
we have yet reached the beginning of the second zero block (nearly 600k)
I don't know, but I haven't heard any noticeable artifacts since the
very beginning.
