Bastien,

	I'm not sure what to set the defaults to in gstreamer-properties. I set
"Default Output: Plugin:" to PulseAudio Sound Server"

When I run gnome-sound-properties and on the "Devices" tab, set the
"Music and Movies" sound playback: USB Audio and hit the test button, I get:

sound-properties-Message: Error running pipeline 'audiotestsrc wave=sine
freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=music':
Could not open audio device for playback. [gstalsasink.c(697):
gst_alsasink_open (): /bin0/halaudiosink0/bin1/alsasink0:
Playback open error on device 'default:1': Invalid argument]


If I select the PulseAudio Sound Server for the "Music and Movies", then
I get a test tone to the speakers, even though the pavucontrol has "ALSA
PCM on front: 1 (USB Audio) via DMA" as the default output.

When I do that with the USB device, I get a Rhymthbox dialogue saying it
failed to open the device.
