What do you see when you do:
  cat /proc/asound/cards
  cat /proc/asound/devices
(from a terminal)

You should see your soundcard and its audio and midi devices. If you
don't then ALSA is not running. 

You should also start a mixer app and make sure the channels are not
muted and the levels are raised. I usually use either Gamix or alsamixer
from a terminal.

How are you testing and what do you force quit?

It could be that an application is already using the audio device and
the app you are using to test blocks (waiting for the device to be
freed). Check to see if something like "arts" or "esd" is running, you
can search for this by doing:
  ps axuw|grep arts
  ps axuw|grep esd

Those are the "sound daemons" for the desktop which you should perhaps
disable (if that's the problem).
