They are called CineSurround 5:1 in the marketing material. When installing ubuntu (9.10 or 10.04 Beta 1), the sound card can only recognise two channel stereo. In addition to the PulseAudio output, I am attaching the output from lshw for multimedia. What should happen is that the sound card is recognised as supporting 5:1 surround sound, appropriate configuration options provided, and sound should come out of all five speakers. At the moment, the sound only comes out of two speakers (on the right). The second problem is that the integrated microphone does not work at all. It is recognised, but no matter how high the input volume is raised, there is no sound recorded. The final problem is that the headset jacks do not work as expected. When I plug in a headset (yes, I have checked to make sure that the jacks are right and the headset volume is set), I would expect sound to come out of the headphones and the to be able to record sound through the microphone. I get no sound and there is no recording. I can only attach one file, so I will add a comment to attach the output for lspci in a comment.
