I don't have one of this machines at right now, however I think the issue is with the nvidia driver provided with Ubuntu 10.04. I was able to get a working audio and 3D acceleration after using the latest driver from www.nvidia.com
I am going to test a beta of Ubuntu 10.10 to confirm it, also I'll get you the output of that command on Ubuntu 10.04 with the Ubuntu provided nvidia drivers.
