kmix doesn't show anything

[Joel Alexandre]

hi, i've just installed my sound card(ac97) with kudzo.
as root there are no problems, but as a user i couldn't access /dev/dsp. so
i changed the permissions of /dev/dsp and now it works. The problem is 
that the sound is too low and i can't use kmix to change the volume. i 
just open it but it doesn't show anything. maybe it's some permission 
problems, but i don't know what to change. As root kmix works perfectly.
could someone help. thanks
