hi! I need your help..

uses RH8.0

I can now here mp3s using xmms, but everytime I log in, with kde, an error message always shows up, saying the sound isn't
detected, after I typed "modprobe emu10k1" in terminal, the xmms works fine. So, what's te problem, maybe I didn't include
the module or something..?

another problem, is the printer. I have HP 845C. I read that this printer woks perfectly fine, but now, my printerwon't print
anything. RedHat recognize my printer model, but when I want to print, it says, that there was an error, and lpd restart is
failed. why is that?

thank you..
