Windows 7: Windows 7 Volume Mixer not showing all sound applications

The Volume Mixer in Windows 7 is supposed to show applications that are running sound, right? Well, mine shows some applications, like Firefox and Guild Wars 2 and Mozilla Thunderbird and KMPlayer. But it doesn't show volume for other applications that use sound like Winamp and ePSXe (playstation emulator).

I'm playing Final Fantasy VIII on ePSXe and the game doesn't have a volume control itself for, say, music and/or sound effects. And I'd like to be able to turn down the sound on the emulator game so that the game volume doesn't intermingle with my music in the background played by Winamp.



Is there a way I can add these applications to the Volume Mixer? Or, alternatively, is there a freeware/opensource program that will allow me to adjust the volume of individual programs?

I am new here so hopefully I have done everything right. I was going to try to list my system specs here in this thread but I followed the link at the top of this Post New Thread page and filled out my System Specs according to the walkthrough.

Can nobody help me with this? I see over 300 Views but nobody has said anything. =(
