Pulseaudio doesn't seem to work in surround/multi-card configuration: (Was: F8/KDE - wrong ownership on all audio devices.)

Here's the weird thing.

$ aplay chan-id.wav
Playing WAVE 'chan-id.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Channels 6

(Plays nothing)

[gilboa at gilboa-home-dev Download]$ aplay -Dsurround51 -c6 chan-id.wav
Playing WAVE 'chan-id.wav' : Signed 16 bit Little Endian, Rate 44100 Hz,
Channels 6

(Plays 5 out of 6 channels [FL,FR,CN,RL,RR are OK])

In F7, when I use the default alsa configuration (aplay chan-id.wav) I
simply hear the first two channels.
