[newbie] A "sound" question

[Andelloria]

Thanks to some great help from two of you out there, I was able to configure 
my sound card (sndconfig) and now definitely HAVE sound... However, when I 
select the sounds that I want, I hear them in "test" mode - but they do not 
occur at startup/shut down - - as I had selected.  When I go back into the 
setup mode, I find that the choices are back to "none"....  Help??  :-)
