Volume adjustment in LISTS ignored AUDIOHW_SETTING values

AUDIOHW_SETTING() defines number of decimals and step size.
This is taken into account in sound menu but ignored in lists
(had been recently fixed in WPS).
This was not a problem so far since all drivers used 0 decimal
places and step size equal 1.
