Hello, I am relatively new to Mac and I have had an Intel iMac (which I love very much) for abouth 2 month. But, I am still using my Windows PC (don't stone me please ) for some application and music production (or something ressembling that...). I really want to get rid of the clutter of having external speakers by plugging the anolog audio of my PC to the Mac and use the Mac as speakers. (Again, don't stone me). But, although I see the bar in the system preference sound panel for the line in, I cannot hear anything from the PC. Is there a way to tell my iMac to redirect the line-in sound to its internal speakers? Thanks!
