Sorry, I was typing this when I was talking; that never works.
I forgot to add that currently, my ALSA mixer is set so that LFE is 10 dB louder, and then that test-file plays its LFE track louder (play with 'aplay -D surround51). If I set all channels equal in the mixer, all is equally loud.
So, the driver leaves things alone, as it should.
Now to find a proper test file, because this one is not played correctly by Mplayer (channel mapping is weird), and it's not AC-3, DTS, AAC, which is what I wanted to test.
