Fedora :: Unable To Hear Audio In ?

One issue that I'm having with Fedora that's stopping me from dropping Windows altogether is that I can't seem to get my audio in line to play directly to my speakers.

Basically, I've got my games console set up so that it uses the desktop computer's speakers as audio output, and is also plugged in to the same monitor and I can change the source depending on what I want to use it for.

I know the hardware works, as the whole thing works fine when using Windows (XP SP3), and I can still record from the audio in line using Fedora (so I can record me playing the game, then play it back and hear it through the speakers), but I've got no idea as to how to redirect the game sounds directly to the speakers.

Interestingly, every tutorial I've found so far suggests that the opposite should be the problem, and that the situation that I want to be in should be enabled by default. That said, I've been tinkering with the audio packages and whatnot long before I tried using the machine for gaming, so maybe I managed to inadvertently remove a package some time ago.
