 From your dmesg here's the problem.
HDA Intel: probe of 0000:00:1b.0 failed with error -16

I'm not a developer so I don't know what that means, just that it is not 
good.

I think this is an issue for some hda-intel cards in kernel version 
2.6.25.  In the cases I have seen the card was working on the 24 version 
kernel, but when they moved to 25 it stopped working.  That is, it's a 
regression.  I don't think there is anything you can do until the 
problem is fixed there.  Using the earlier kernel is probably not 
possible with the rest of the system.  I don't know this, but suspect 
it.  You could try compiling an earlier kernel on your system. 

I'll cross post this to the alsa-devel mailing list so the developers 
become aware of the problem.
