Multiple audio devices, stereo mix and a microphone

Hello,

I'll try to explain this as simply as possible... Currently, I have speakers, headphones and the headphone microphone plugged in. I'd like to record my Skype conversations using stereo mix, but stereo mix only picks up what goes through my speakers and not what goes through my headset. I've tried tinkering with the settings and haven't been able to get stereo mix to record what goes through my headset instead of my speakers.
How do I get stereo mix to record headphone audio instead of speaker audio?

For the past few hours, I've also been trying to get Audacity to record both stereo mix and my microphone. From what I've read, Audacity can't record two inputs at the same time, so is there a way to combine stereo mix and my microphone?

I'm using the latest Realtek HD drivers, if that helps any.

Thanks for your time.

You might want to check out VAC(Virtual Audio Cable). It is not a "free" program, so depending on you needs, it might help. here is a link to info about it:Virtual Audio Cable - Wikipedia, the free encyclopedia

I used it myself to share music I was listening to over video chats. The program can be used in a number of ways. I no longer use, since I currently have a laptop with Stereo Mix, and that meets my needs just fine. Hope this helps.
