Oops, the valid values actually begin at 3. This channel map is correct:
3:front left, 4:front right, 5:rear left, 6:rear right, 7:front center, 8:LFE
PulseAudio's map:
> front-left,front-left-of-center,front-center,
> front-right, front-right-of-center,rear-center
would be the equivalent of 3,12,7,4,13,11. This is not what the driver tells
it; this appears to be a bug in PulseAudio.
