BUFFER_LENGTH_: 
This field shows the remaining length of data that needs to be 
read from memory; Initially set by S/W for total of bytes that are valid and is 
decremented by H/W as reads are issued. Software must end buffer at the boundary of 
a audio sample with all of channel values of that sample are valid.
