This is because the volume control is implemented in software by scaling the
audio samples that are sent to the device.

By default though, the alsa plugin is set to use 200ms of buffering in the
audio device - to prevent buffer underruns and dropouts.

You can try setting your sound output to 'Custom' and give it a value like
'alsasink buffer-time=100000' or smaller, and you'll get faster volume changes,
at the expense of possibly more dropouts.

The buffer-time property is in microseconds.
