The sound doesn't work after a fresh install because the "External Amplifier" option is turned on by default. You can turn it off by opening "Volume Control" in Applications>Sound & Video and enabling "External Amplifier" in Edit>Preferences.

Now would also be a good time to make the Volume Control Applet modify headphone volume because it seems the headphone jack's volume is unaffected by the Master Volume. PCM works too, though I like being able to control both separately.
