Bug#711049: gnome-settings-daemon: replugging a usbaudio device causes gnome mixer to defautl to internal audio, while pulseaudio uses the device as sink

[Kim Twain]

Package: gnome-settings-daemon
Version: 3.4.2+git20121218.7c1322-3
Severity: minor

Dear Maintainer,
When plugging a usb audio dac/headset, gnome switches to it by default. 
However it sometimes happens to accidentally unplug the usb cable and replug it shortly thereafter. 
What happens next is that pulseaudio returns using the usb audio device as sink, but gnome doesn't and switches controlling the default audio sink, so you won't be able to control the volume of the usb audio device anymore. Trying to set the volume in gnome affects internal audio, which isn't being used.
I hope this is the right package to fill the bug against :) (I was unsure about it being gnome-control-center)
