Hi,
MS will send down the volume levels for channel 0 and
channel 1 only. channel 0 indicates all the left side
channels, (front left, surround left and etc). and
channel 1 indicates all the right side channels.
The reason why you get the same level for both is
because you change the volume which will apply for the
both channels. If you change the pan, you will see the
difference.
