Gettunervolume Not Working

Hi 

for my game i would need a working “GetTunerVolume”
API says i get data from -1 to 1

 

but with the code

 

v = r:getTunerVolume()

v = 10*math.log( v )

 

i get v something between -25 and 0

and big jumps … not really sensitive

 

any clue… this problem persists now since also over 1 Year.

will it be fixed?

 

thx

chris
