On a cold boot with pulseaudio set to not autospawn, logging in to tty1, with the speakers plugged into the back of the computer (ie 'not' headphones) and doing speaker-test -c2 -Dplughw:0 I heard white noise alternating between the left and right speakers. The test called it 'pink noise' but what I heard sounded like the ocean (without the undulations).
