Sound problem, again

[Eireann]

I just tried unplugging it again, while something was playing. Not only did I hear no sound from the rear speakers, when I plugged the headphones in again, I heard nothing from THEM.

I'm almost positive it's Realtek, yes. How can it be reconfigured?

If it's Realtek, you should have an orange speaker symbol in your system tray (not the Windows mixer thing; this one is a tacky orange color, it'll stand out). You might have to click the arrow to see it. That will lead you to speaker configuration stuff. Double-check the jack assignments in particular -- you might not have everything in exactly the right jack and have to reassign a few things to make it work.
