We opted not to allow the user to change input levels on SDI (serial digital
video) inputs. These levels are best preserved in their original state
during capture.

You could also implement it in software, since you do the conversion
int->float, it's just one multiplication more, thats pretty cheap; in fact,
it can turn out to be a BONUS speedwise, since it gives you another 'stage'
to schedule the pipeline.
I think it's too bad theres is no standard properly for level metering in
general, some boards to that in hardware as well, theres no need to process
any audio at all (especialy for input)
