For the record, the "00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev a2)" does not work out of the box on Ubuntu 8.04.

  Model: "Hewlett-Packard Company Audio device"
  Vendor: pci 0x10de "nVidia Corporation"
  Device: pci 0x03f0 
  SubVendor: pci 0x103c "Hewlett-Packard Company"
  SubDevice: pci 0x2a61 
  Revision: 0xa2
  Driver: "HDA Intel"
  Driver Modules: "snd_hda_intel"

Yesterday, I got one of those extra-cheap (and fairly good) HP Pavilion boxes and I run into a problem when I tried to get the sound subsystem to work on Linux. Long stories short, I had to recompile ALSA 1.0.17 by hand with the --with-cards=hda-intel parameter, after which everything started working perfectly.

I wish someone had written this before, so I could have saved a couple of hours trying to realize what was failing.
