The system can recognized the hardware and I can even run the Realplayer for linux without any error messages, but it can't make any sound, or even noise. I have googled a lot but still can't get it work.
Open the mixer window and check the sliders and switches. It should say "hda nvidia" at the bottom.
The box I'm responding with has the nvidia MCP55 chipset. Should be similar to yours - I've never had a glitch.
