  Regarding bindings as you explained"bindings.x
y" or "bindings { x y }" maps channel x of this device to
 channel y of the slave device.

 I didn't understand channel x of this device means is it the real sound card??? which
is the current device ie., channel x of this device means???

 I didn't understand channel y of the slave device means??..  ie., which is slave
device here???? 
"This device" is the virtual device that is defined.
The slave device is the device whose name is specified with "slave.pcm".
