OK - I am now getting more confused:

gnome-device-manager tell me: (null) sound card

lshw finds:

Above "sane level for headphones" comment is for : Dell Studio XPS with 
2.6.30. Which seems to be consistent with Ubuntu's statement that the 
audio driver was not in my kernel but was a "oversite" that would be 
fixed in future upgrades/updates as it appears to be in 2.6.30.

Update Manager does not show me that 2.6.30 is available.  Should I be 
trying to upgrade to this.  As I indicated in an earlier post I am not 
new to linux (Red Hat) but these are my first experiences with Ubuntu 
and am a bit confused about the fetching deb files, apt-get and "Update 
Manager" and any differences in usage among these for packages vs kernels.

I see that "deb" files are available for 2.6.30 (and .32 also) for 

"The Ubuntu kernel guys have released an official build of the 2.6.32 
Linux Kernel.
The .deb files should work with both Ubuntu and distributions based on 

The included kernel files have been compiled using the generic ubuntu 
Note: nVIDIA ForceWare drivers are automatically installed using DKMS 
(which is included in Ubuntu 8.10 and higher including 9.04 and 9.10)"

Is this reference to the nVIDIA drives relevant with respect to my 
nVIDIA sound card?

The instructions for download is clear but the instructions merely state 
"install" them which I assume means use dpkg.  Do I have do anything 
with the grub loader.

Is this what I should be doing or will these releases be available to me 
   soon via "Upadate Manager"? I am a bit nervous fooling around with an 
almost working system just to get audio working if this will be getting 
   fixed in a normal upgrade.

Sorry for such a long post and I am most appreciative for all of the 
help.  You guys are really great!
