Yes, certainly I would say permissions.
In redhat there is a file called /etc/security/console.pems which sets up permissions and ownship for many files and devices upon boot. You would have to modify this file. Perhaps there is a GUI will do this for you, but that I could not help you with. There is no better tool than vi :-)
In suse (PPC 7.3, i386 8.0) a similar file is called /etc/permissions.
You neglected to say what distribution you used, or whether you built your own uniquely. Such information can be helpful.
You may or may not have an audio group, which will help control usage, the versions of Suse I use have one, my RH 7.3 does not. All you must do is make sure that the general user has permission to write to /dev/dsp. Note that /dev/dsp in Suse appears to be a link to /dev/dsp0 (and as such the pertinent file to check) while on my RH system /dev/dsp is the real device.
