Not able to control volume via amixer

Hi all,

I am not able to control the volume via amixer. The amixer output doesn't show the pvolume capability and volume range.
Can someone please help me to control the volume via alsa.?
Below is the output of the '$amixer scontents' command:

firefly@firefly:~$ amixer scontents
