Is there anything alsamixer is unable to load? Try as root too, you may be missing a user group. There looks to be a bundle of information on the Ubuntu forums about this as well so that may be a good read too. Otherwise, make sure your system is up to date and running the latest kernel (not sure what the Hardy roadmap looks like so I am unsure as to what the lastest is, just run apt-get install dist-upgrade)
