Plugging in USB headset, there is unexpected behavior.

Changing the output device in System > Prefrence > Sound to "USB Speakers (ALSA)" redirects all streams to the usb headset except firefox/flash.

A manual non-persistent workaround for this is explained in Answer #56282
pavucontrol is needed (not included) to have sound output directed from firefox to the USB headset, otherwise built in speakers are used. Also, There has to be a stream (an instance of a program with audio output) running to redirect it to the speakers.
