Don't apply this; more survey of alternate sound cards shows
that DSP_POST does not work as well as advertised everywhere.

When we get down to the last fragment or two in our output
to the DSP, we should use the SND_DSP_POST ioctl to let the
sound card know to flush those fragments.  This allows us to
precisely know when the buffer is empty, and fixes another
set of winmm tests.
