security clearance? Not really sure what you mean.In the original dos version of the game, you have to input a password. There are some password lists around if this is your problem.
In the Wizardry Archives version, you do not need a password. Also, you don't need to have the cd in the tray. With the original release, I think you do.
Probably the reason your sound does not work with the overflow patch is because you don't have a legacy soundblaster driver/or compatable card.
There are some dosbox.conf files around that have been made to help get the game going. Try one of those.
To get any real help, you need to give us some more information about what version you are playing and where it came from, what problem you are exactly having.
