So the thing to note here is that your installed 2.6.25 kernel lacks any 
sound modules loaded.  In fact, not even the glue layer module, 
soundcore.ko, is loaded.  This is indicative of [at least] one of two 
common errors:
1) There are, in fact, no sound-related modules installed in 
/lib/modules/2.6.25-2-386;
2) A self-compiled (from upstream ftp.alsa-project.org or a snapshot 
from Takashi's kernel.org area) alsa-driver is fubar.

You can pretty easily regain sound in your installed Ubuntu Intrepid by 
reinstalling the linux-generic package, ensuring that the latest 
available Intrepid kernel is installed, and afterward, rebooting.  At 
this writing, you'll need at least linux-image-2.6.27-9-generic from 
intrepid-security installed.
