volume: print actual produced values, not bytes

Browse source 
`map.data` is a pointer to a byte array,
we need to first cast it to the pointer to the expected element type,
otherwise we will get not what we are expecting.

I have stumbled into this in https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5063#note_2007447
