Record from Headset - valid volume range values

Question

Does anyone know what the valid range values are for IN1R volume and AIF1TX Input Volume?

#Record from Headset to AP

amixer -Dhw:0 cset name='IN1R Volume' 20

#amixer -Dhw:0 cset name='IN1 Digital Switch' on

amixer -Dhw:0 cset name='AIF1TX1 Input 1' IN1R

amixer -Dhw:0 cset name='AIF1TX1 Input 1 Volume' 32

amixer -Dhw:0 cset name='AIF1TX2 Input 1' IN1R

amixer -Dhw:0 cset name='AIF1TX2 Input 1 Volume' 32

amixer -Dhw:0 cset name='Headset Mic Switch' on

Many thanks.

Use amixer's cget command to query the controls. 
 $ amixer -Dhw:0 cget name='IN1R Volume' 
 numid=7,iface=MIXER,name='IN1R Volume' 
 ; type=INTEGER,access=rw---R--,values=1, min=0,max=31 ,step=0 
 : values=20 
 | dBscale-min=0.00dB,step=1.00dB,mute=0 
 
 $ amixer -Dhw:0 cget name='AIF1TX1 Input 1 Volume' 
 numid=250,iface=MIXER,name='AIF1TX1 Input 1 Volume' 
 ; type=INTEGER,access=rw---R--,values=1, min=0,max=48 ,step=0 
 : values=44 
 | dBscale-min=-32.00dB,step=1.00dB,mute=0
