Since external speaker worked and internal does not, I suspect it could be a configuration problem ie, kernel + userspace component all ok....so how about this:
http://ubuntuforums.org/showthread.php?p=9488763 For your case: 1. copy the conf file out (since u have installed the backports. 2. deinstall the backport alsa module, and reinstall the latest alsa modules. 3. And modify the conf file to use the same parameter as that of the backport version. Perhaps I may be wrong somewhere...but u can give it a try?
