I just tried Ubuntu 15.04 which embeeds pulse audio 6.0.
In the sound settings panel, I can switch to 2.1 profile, and within test panel, everything works just fine : Left, right and subwoofer.

*But* when I launch any sound application, there is no sound through subwoofer.
I tried Gnome videos, vlc and firefox.
Is there something wrong with the applications?

I think this is weird because if the application outputs stereo tracks, then pulse/alsa should be able to generate a subwoofer track (mix+lowpass) and then output 2.1.
Am I wrong?
Any configuration test I should try?
