Thanks. I have tried alsamixer and it seems not to provide interfaces. 
amixer provides interfaces.

amixer  sset Master VOLUME

So the next step is to write a simple script to run amixer in some way 
when key pressed.

Please allow me to another question. I want a volume bar to be displayed 
in the center of the screen when adjusting volumes, but not in the panel 
because it is too small. What should I do?

Thanks in advance.
