[opensuse] How to get youtube sound

I now get Youtube video, but I get no sound. Should I plug my earphones into the light green audio jack or one of the other 5 jacks? Do I need to configure anything in Suse 11 to enable audio output? How do I adjust volume? I apologise for my total lack of audio expertise.
