When playing RhythmBox or using the test sounds. No sound comes out of the rear panel for the speakers, however sound does come out of the headphones on the front panel.
Audio did not worked after I fresh-installed Ubuntu 12.04RC2 until the second-to-last update. Then it worked. Then the last update perhaps made it not work again.
In Sound Settings... I tried setting the Analog Audio to different types, i.e. Analog Stereo Outputs and Analog Surround 5.1 Outputs. Both worked through the headphones (e.g. the front left and right speaker tests), but nothing through the rear panel.
If I use the Pulseaudio Manager and crank up the Audio to 400 %, I can hear a faint, distorted audio from the speakers (also turned up). This could simply be cross-leakage from the front panel circuits...
