Sound doesn't work if I don't use root
I have recently installed Slack8 and all seems to work very well except from sound. If I login as root and go into kde or gnome the sound works perfectly. However, when I login as other user (not root) and I go into kde or gnome, the sound does not work at all. I don't really know what can be happening so I would be grateful if somebody could give a piece of advice.
