/dev/dsp cannot be opened permission denied
 

Hello anyone I'm quite new to Linux so pls don't flame me :)
I've decided to start w/ the Slack distro in order to learn how linux works but sum probs obviously raise.
My prob is I got a c-media audio sound card and after reading the doc I manged to install it but It works only if I log as root. So I tried to issue these commands:

giorgio@AceSlack:~$ ls -l /dev/dsp
lrwxrwxrwx 1 root root 4 Dec 26 04:02 /dev/dsp -> dsp0
chmod 755 /dev/dsp
chmod 6755 /dev/dsp
chmod 755 /dev/dsp0
chmod 6755 /dev/dsp

But none affected the permission, and I had previous probs too with permission when I try to mount cdrom for users too.
I prolly dunno which file I should set the permission to
I'm really confused can some1 help me pls?

Actually I made it !!!
I found a thread about it in tux racers so I typed chmod 0666 /dev/dsp
But got no clue what it does :confused:

and you can add a users and or umask=000 entry in your fstab for the
drive you want users to mount. there's lots of threads about that here
too.

Thx for the reply but is it unsecure using chmod 0666 with /dev/dsp?

Here is a link that will help with Slackware.
