sound help

In the sound properties I have the arts checkbox off for both users root and another, In root I hear sound but in the other user there is no sound.

In root when playing a game there is no sound

In the other user when playing the same game I hear sound

With the arts checkbox on in root the sound for the game is delayed e.g. I jump, then in a few seconds I hear the jumping noise. and in the other user when that check box is on I get an access denied message for sound driver.

May someone please help me fix these problems.

Thanks in advance!

I forgot to mension Im using KDE, and distribution based on Slackware Linux.

I and others possibly could help, although you're being pretty vague on you're description of what the program you're checking the box off in, and what game you're using. Here's my advice... you shouldn't be running a game as root though either. You should barely ever touch the root account unless you seriously have to. I can possibly help you on your permission denied error. This error might be coming from /dev/dsp, or /dev/mixer. Which ever it is, the case could be that it is chmodded so that you (and any other user other than root) can access this. You might want to try chmodding /dev/dsp to allow regular users to 'R'ead, and e'X'ecute. (I'm not 100% positive on this, although it's worth a shot.)

In shell assuming you're in the /etc/sudoers file... if not follow the commands below this one.
$ sudo chmod og=rx /dev/dsp
Logged in as root (or su'd)
$ su
# chmod og=rx /dev/dsp
Hope this helps your problem with the sound. As for the game, it just might be trying to process the signal coming from the soundcard so that it lags for a second then the frames catch back up with the game. Although I'm not 100% percent sure =)

Thanks for you help! That didn't work though. Here is the error message I get on the other user when enabling the arts option

Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (Permission denied)
The sound server will continue, using the null output device.

I searched this and the game I play if possible communciates with the sound card directly.

Others have come accross similer problems but what I searched I could not find an answer. Iam problably searching for the wrong keywords again

Is your normal user a member of the audio group?

If not, you cab add the normal user tothe audio group via KDE's user manager: Click on K, click on System, click on user manager. You have to provide the root password. Then select the normal user with a double click and make sure the audio group checkbox is selected. Save your changes and close the user manager. Now log out of your session and log back in. Your sound should work now.

If not, check the volume settings with one of the mixer programs.
