sound card verified but won't play sound
I recently installed fedora core2 onto my athlon xp 1700+ w/ soyo dragon plus mobo. Fedora detects my soundblaster audigy card correctly, but when I play the test sound, nothing plays. On my windows partition, the same thing happened, and somewhere I had to uncheck a checkbox saying 'digital input only' to make the sound work. I'm not sure where I could try something like that here. I'm using borrowed speakers from a friend, real cheap, that came with his dell computer.
Suggestions? If i forgot to give any important information, just remind me i'll post it.
