Just FYI, this is the new softvol PCM plugin for alsa-lib.  In the new
ALSA this is used to create the volume control for (cheap) devices that
can't do it in hardware.

I'm not really a DSP expert but I figured this might be of interest with
the various software volume related threads.  Any comments on it would
be welcome.
