This shows the input channels (i.e the one of your stream) and the output
channels (the one of your device) and the multiplication factors for the
input channels to get to the summed output samples.
We also see the channel mapping that was specified for your stream:
lfe,front-left,front-center,front-right,rear-left,rear-right
And your device is surround40:0 which is the mapping front-left,front-
right,rear-left,rear-right.
The problem I see here is that front-center is mixed into the rear
channels. Is that the problem you were trying to point out?
