Sound works only in run level 5, not run level 3 (Fedora 8)

[Chris G]

I usually use run level 3, i.e. I do a console login and then run
startx from the command line.

Having just moved from Fedora 7 to Fedora 8 my sound no longer works
when I use run level 3 as above.  However if I switch my system to run
level 5 so I do a graphical gdm login the sound works.

In run level 3 the sound doesn't work because of permissions, if I
manually set the permissions on the devices in /dev/snd to 0666 then
sound works in run level 3.  However when in run level 5 the sound
works with the permissions on /dev/snd devices at the default 0660.

I've compared the output of "ps -ef" for the two run levels and I
can't see any significant differences.

Can anyone else explain what the issue might be?
