I haven't followed this discussion closely, but what sliders are enabled 
in Gnome sound settings is related to what profile is selected for that 
card. So if you select the 2.1 profile, "Balance" and "Subwoofer" will 
be enabled (and "Fade" disabled), but in a 4.0 profile, "Balance" and 
"Fade" will be enabled (and "Subwoofer" disabled). Is that answering 
your question?

For the record, PulseAudio does not yet use the new channel mapping API.
