This workaround worked for me: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules
In some similar bug reports, other people solved their problem with this: https://help.ubuntu.com/community/HdaIntelSoundHowto I have to say this was really painful for me: I had to search for a dozen hours before finally being able to use my headphones on a very common computer (Asus N73S). How come this bug is still not resolved in Oneiric?
