This is to the guy that only gets sound as root:
As root:
modprobe sound, if no reply modprobe emu1k01
if it doesn't return anything or returns an error then go download the driver and install it. Then do the following.
You will need to load the kernel module everytime if you don't add it to /etc/modules.conf. I would recommend adding it to modules.conf
chmod 755 /dev/dsp /dev/dsp1 ; ln -sf /dev/dsp /dev/dsp1
that should solve the problem
