I have a problem every-time I boot up my computer it uses the internal speakers, so I set the Sound Effects to Digital Out, Output- Digital Out- Built-in OutPut, Input- Digital in Built-in Digital Input after I done that my z-5500 works fine but the next time I boot my computer again it uses the Mac Pro internal speaker instead of the Z-5500 is there any way to save the setting so that I don't have redoing these steps every-time I boot-up my computer, before I installed Snow Leopard I did not have these problems in Leopard but ever sense I installed snow leopard the problems began. Is anyone else having this issue.
