    What did you remove a file or what, just reinstall it?
    Go back through your terminal commands and do the opposite of the thing that broke it. :p

    A thread on the ubuntu forum recommended adding this to the modprobe.d directory.

    /etc/modprobe.d/sound.conf 
    options snd-hda-intel probe_mask=0x102

    I removed that and performed alsa force-reload and restarted.

    Still no sound.

    Run 'lsmod' to double-check the snd-hda-intel module is getting loaded...

    You could load each of the alsa associated kernel modules manually, but I think the handiest solution is to just drop to a root shell and run the following(dpkg command just a precaution - I doubt you run the open sound system). You should also check your modules using lsmod and check for lines like snd-hda ect.
    # dpkg-reconfigure linux-sound-base ( select ALSA here )
# alsaconf ( may not be present on the latest version of Ubuntu )

    Failing the above, you need to manually load each module for the chipset, and place them
    in the modprobe.d directory. Oh, and try not to mess with sound in Linux in the future : D

    Make sure you check the required modules are placed under /etc/modprobe.d/alsa-base.conf too
