now the only problem is, how do i make the usb device default for all audio output?
HI,

Were you able to get sound through it? I don't mean as your default device but at all, as a test? I'm attaching a short python script to enumerate your output and input devices as gstreamer would see them. Be interesting to see the output as to whether gstreamer can see the device. If so you could potentially route your sound out through it in addition to the main output (which you could always run to a null headset).

Code:
#!/usr/bin/python

import gst

sink=gst.element_factory_make("pulsesink","mysink")

sink.probe_property_name("device")
devs = sink.probe_get_values_name("device")

print
print "sink devices"

for dev in devs:
  print dev
  
sink=gst.element_factory_make("pulsesrc","mysrc")

sink.probe_property_name("device")
devs = sink.probe_get_values_name("device")

print

print "source devices"

for dev in devs:
  print dev
  
print
