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: /dev/dsp: Permission denied
