Can't get MCP55 based sound to work in ALSA.

Hi All,

I have onboard nvidia MCP55 sound.   I can get it to work using OSS, but I also use a USB headset which is sort of...  non-functioning with OSS.   So I would like to try to get it functioning with ALSA.  I have tried everything I can think of and read the forums.  One was marked solved but didn't say how.  Below is an output of every test I can think to run....    if you have any ideas it would be appreciated.   If there is anything you need to try please let me know.   I believe the MCP55 uses the snd-hda-intel driver.

Re: Can't get MCP55 based sound to work in ALSA.

Ok, I got it to work... I reinstalled the kernel and rebooted.  I have _no_ idea what that did.   Interesting.
