Bug Description

I've tried messing around with some settings, made sure nothing was muted, ect
but have no sound in my USB Plantronics DSP 500 head set. The sound worked fine
through my speakers, and using a nvidia soundforce card but not in the headset.
The headset works perfectly well on windows with the drivers it was packaged
with..Someone assisted me in fixing the problem, by going into System -->
Preferences --> Multimedia Systems Selector and setting the Default Audio sink
as custom and the pipeline as "alsasink device=plughw:1,0" and then going into
the terminal and typing "sudo modprobe snd-usb-audio". There were also some more
commands that he told me that I can't quite recall what they were.. He then told
me to unplug my headset, reboot and then plug it in again. I did so, and came
back and the sound was coming through the headset like it was supposed to. Ok so
then I reboot to test something out, I come back and try to play my songs and
its not working through the headset again, but still works in the speakers..

hope this bug report helps and that better USB (sound) support is added in Breezy

That was the output

NOTE : I got the headset detected again yesterday, rebooted into windows xp then
came back to ubuntu in the morning, and the headset was no longer detected.
Seems booting into XP will lose my detection of the device (not sure why). But
hopefully this will help make the bug seem more clear.

Please correct your syntax; it's /etc not /ect.

It seems that hotplug is not loading the snd-usb-audio driver as it should.

So the USB headset works if you hotplug it, but not if you reboot
the system with the USB headset plugged in?
