if volume componenterter component is not selected then sink component will not work, even if specified
output file name check
getting audio source handle
getting volume componenterter component handle, if specified
getting sink component handle - if reqd'
output buffer size calculation based on input dimension speculation
if tunneling option is given then set up the tunnel between the components
sending command to audio source component to go to idle state
in tunnel case, change the volume component and sink comp state to idle
if tunneling option is not given then allocate buffers on audio source output port
in non tunneled case, using buffers in volume component input port, allocated by audio dec component output port
allocating buffers in the volume componenterter compoennt output port
send command to change color onv and sink comp in executing state
sending command to audio source component to go to executing state
state change of all components from executing to idle
sending command to all components to go to loaded state
freeing buffers of volume component and sink component
freeing buffers of audio source input ports
closing the output file
