That is hard to avoid, the audio output buffers a lot of sound a data and there's not really any way to change the data by software after it has reached the sound subsystem/driver.
Though with -ao dsound I'd expect there never should be any reason to use softvol, since directsound should do the mixing in a better way in software/the driver if I remember correctly.
The feature is mostly for more lowlevel APIs.
