To quote <http://mailman.alsa-project.org/pipermail/alsa-devel/2013-July/064461.html>:
You don't need such symbols to use a rate.  These symbols are intended
for often-used rates.  As long as only one or two drivers use a rate,
they can just set KNOT and install a constraint.

How many driver would actually use it?
