I reading this http://manuals.opensound.com/developer/SNDCTL_DSP_GETOPTR.html
It says: "In mmap mode (only) the ptr field tells the location where the next

In my opinion that means that we have a mistake in our code and the following
patch should be applied. But I am not sufficiently familiar with this code.

P.S. leading (indenting) whitespace in this file is a mess.
