Default Audio capability of nVidia Quadro NVS 160M not recognized by system

Hello, everyone. I have an E6400 laptop from Dell, running Ubuntu 10.10. The GPU is the nVidia Quadro NVS 160M. I also have dual-boot, and in Windows 7 the NVS 160M sends both video and audio beautifully through HDMI (DisplayPort-to-HDMI) to my external display/receiver. However, in Linux, there is a problem with the audio. It seems the nVidia card is able to only send video, and not the audio. I have read the numerous other discussions on this (including the awesome HDMI audio documentation from Stephen Warren), and found that this issue may be somewhat different than what most users typically report.

In my case, it seems the sound card of the NVS 160M is not even picked up by the system; it does not show up lspci (see output below). Thus, I can't even start to configure the device. I do not know how to proceed to fix this, hence, I am posting here to get a kick in the right direction. Have anybody seen this before?

nVidia version: 270.29
Alsa version: 1.0.23
Linux kernel version: 2.6.35-28-generic
