The term 'soundcard' is used loosely to sometimes include onboard sound as well as cards for the sake of brevity.

It's true, you do not have a removable card, none the less you have a chip that serves the same function. Find out which one it is. It is entirely possible that it has been misidentified by Linux (nothing is perfect) but if it's new it probably just needs drivers. I would follow through with fingers99's good advice of installing ALSA.

Go get a .deb

Where? you ask - here_. http://packages.debian.org/stable/sound/

If you need assistance getting it installed you can go here:
Debian home page www.debian.org

Once you see how easy .debs are to install you will be impressed there is also apt-get. Neither are flawless of course!
