...I am passing along the email below, which I received this morning,
FWIW.  I have not yet tried what he suggests - it sounds promising,
though I note that ALSA on my HP laptop (zd7000) system reports
finding a SigmaTel STAC9227 rather than the 9200 he mentions.

  I got the Nvidia MCP51 high definition audio to work with Linux.  I'm
  assuming you have the Sigmatel STAC 9200 on it.  If you do, here's how
  you can fix it.  Pasted is the post I've been pasting on a lot of forums:

  I finally got my sound working after a month of searching various posts!

  I have the NVidia MCP51 High Definition Audio with the Sigmatel STAC
  9200 chip on it.  It came with my Gateway MT3421 laptop.

  I had given up on sound because everyone on forums had given up, but
  there's a patch for fixing this sound card on the alsa-bugs site!

  Just go here and look for the post with the patch and follow the
  instructions: http://forums.fedoraforum.org/showthread.php?p=868053

  A couple things:

  1...you don't have to remove all alsa packages like he said in step 1.
  All I did was remove alsa-lib and alsa-utils.

  2...the patch file is at the bottom of the post as an attachment.

  I hope this works for some of you!
