Angry dev/dsp can't be opened

Hi all!
I've been trying for a while to make my sound to work but no results. When I start the computer I get a message like :

"Error while initializing the sound driver.
dev/dsp can't be opened (Permision denied)
The sound server will continue using the null output device"

What I did was changing permission for /dev/dsp from 640 to 666.
Same I did with /dev/audio .
When I try /dev/dsp I get same message like before:

bash-2.05a# /dev/dsp
bash: /dev/dsp: Permission denied

Thank you

Im not sure if it will change anything but try chmoding 666 on /dev/mixer and /dev/sequencer as well. Where exactly do you get the message you cited in the first post? While booting? In system console?
