It's probably a question about permissions.
You should be in the right group to be able to listen to audio. If you have an audio group then pu your user in that group.

This is not recommended but if you just "want it to work" you can change the permission on your devices you need to play audio
check in you /dev directory after
/dev/mixer /dev/snd/ /dev/sound
and do
chmod 777 /dev/mixer
chmod 777 /dev/snd/ -R (because it's a directory, R for recursive)
and so on..
you also need a mixer, aumix for instance is easy. you have to boost up both pcm and volume
good luck
