It sure does, but I can't reproduce it on my P4 based system which is
normally very picky about denormals - CPU load is around 2.5% all the
time. Also checked all parts of the code that could produce denormals:
the HP processing filters, the k-meter and c-meter DSP code, and the
volume controls. All have denormal protection.

* Is the CPU load you mention the one measured by Jack, or some other ?
* Try to find out which controls affect the CPU load. E.g. what happens
when you have a signal but the volume is set to off etc.
