With this implementation the #amixer cset numid=16 3 numid=16,iface=MIXER,name='PreDriv Playback Volume' ; type=INTEGER,access=rw---R--,values=2,min=0,max=209,step=0 : values=3,3 | dBscale-min=-12.00dB,step=6.00dB,mute=1 The min and max values are from 0 to 209 and they r repeating for every 4 steps Can any one explain this

With this implementation the min and max values seems to be shown like 0 to 60 instead of 0 to 3 and the range is repeatring between 0 to 60 Means 4 again 0 and 7 a bit max, its repeating..
