I can confirm that worked... just rebuilt the modules and sound works correctly.
For anyone wanting to do the same do the following: Install linux-source: sudo aptitude install linux-source Make a directory where you can use to extract the source: mkdir ~/xyz cd ~/xyz Exact the source to that directory: (Check the version of the tarball prior to this) tar jxvf /usr/src/linux-source-2.6.20.tar.bz2 Enter the root of the kernel source: cd linux-source-2.6.20 Copy the config file to the source tree: cp /boot/config-2.6.20-15-generic .config make menuconfig (When you get the menu, just exit) Enter the directory where the intel driver source code is: cd linux-source-2.6.20/sound/pci/hda/ Now find the line number to edit, and or check if it needs modified: grep -n '#define AZX_MAX_CODECS' hda_intel.c You should see an output simiar or the same as: 201:#define AZX_MAX_CODECS 3 Now edit the hda_intel.c file with your favorite text editor, and change the 3 to 4, and save the file. Build the new modules: make -C ~/xyz/linux-source-2.6.20/ M=$PWD modules You will have two files: snd-hda-codec.ko snd-hda-intel.ko Now copy those to the kernel modules with: sudo cp snd-hda-*.ko /lib/modules/2.6.20-15-generic/kernel/sound/pci/hda/. Reboot... You should have sound..
