/dev/dsp insufficient permission error after installing kde3.1


I use Mandrake 9.0 currently (since I am new to Linux, it is the first distro I have used). I couldn't wait for 9.1 before I got to use kde 3.1, so I downloaded the source and installed it. Not, whenever I log in as any account other than user, it tells me that the arts sound has been redirected to /dev/null because I have insufficient permission to access the device.

The most obvious solution I thought would be to chmod 666 /dev/dsp. I tried this, but whenever I reboot permissions revert to the normal, and even when I don't reboot, when I log-in to KDE again it gives the same error. I have not had this problem in Gnome, which is the standard 2.0 rpms that Mandrake 9.0 ships with. If anyone can help with this I would greatly appreciate it.

One way of doing this is to modify /etc/security/console.perms appropriately. The appropriate lines in mine, which may not be optimum (since I did this a couple of years ago) are:

<sound>=/dev/dsp* /dev/audio* /dev/midi* \
/dev/mixer* /dev/sequencer \
/dev/sound/* /dev/beep

<console> 0666 <sound> 0666 root
