MOnitoring what comes from the line in on a mac?

[Dan Eickmeier]

Hey all, if I wanted to hook up a mixer to the line in on my mac, I'd  
want to be able to hear what is coming through that.  In Windows, I  
could unmute the line in in play back, but haven't  been able to find  
anything similar on the mac.  Any help would be appreciated.
Thanks.
