Depending on the situation, I use either my speakers or my headset for audio output. Given that my headset is an USB headset it behaves as its own audio device.
Currently I switch between audio output devices by clicking on the speaker icon in the upper right tray, where I select Sound settings, goes to the Output tab and there choses the device I want.
What I wonder is if there might be some easier/quicker way to switch back and forth to my USB headset? Perhaps a dedicated tray icon, a key mapping, or so?
I am running Ubuntu 10.04, with the default Gnome desktop.
