Aliasalpha: What is it with you and sound problems?
What brand of soundcard do you have? Have you used the advanced settings in the recording sources panel to display all options (I assume 7 has something like this)
Yes, I got it to show all hidden and disabled audio devices, and Stereo Mix did not show up. My Alienware documents say I have an Integrated High Definition Audio Driver, so I'll see if I can find a website where I can download drivers for it.
UPDATE: My Alienware support site says the full name is
INTEGRATED HIGH-DEF AUDIO NVIDIA C55-MB, though I'm having some troubles finding the correct driver for that.
ANOTHER UPDATE: What do you know, driver update was on CD! Man, I've got to stop freaking out when I get small errors like this. I'm like the guy who locks himself out of his own car, so he needs to pay some service an insane price so they unlock the car for him. Thanks for the help anyway.
