On my machine, while running 3.8.0-17-generic, the Sound Settings panel correctly displays "HDMI / DisplayPort" when the HDMI cable is plugged in, and hides it when it's not.
Under 3.8.0-19-generic, the option never shows up, even though "aplay -l" lists the HDMI output under both kernel versions (whether the cable is plugged in or not).
