FIFO was being read every sample after the "almost full" state was
reached. This was due to an incorrect placement of the parenthesis
in the while condition check.

Fixes tags please in future. I've applied this to the fixes-togreg
branch and marked for stable with a fixes tag of the last patch to
touch that line (which isn't really correct, but a backport would require
that patch anyway in addition to this one).
