To further elaborate my question , when I do an aplay the control comes to
my plugin and I can play the audio samples, but I want to some mechanism
using which,

#amixer -D my_control_plugin cset numid=1 100 //say volume control

should also come to my plugin, a control plugin may be? How do I do this, I
dont know any way to specify the plugin path while using amixer command.
