Recording problem (with pics)

Hey

I'm having a problem as follow:-

The problem is in recording the sound that comes from playing media in the computer or anysound comes from the computer without using the microphone, but by changing recording option in the panel.

I used to go to Yahoo messenger for example and clicking ((talking)) and leaving the computer sending the media, without letting the microphone to send any sound, I did that by:



then, choosing the recording option under "Adjust volume for"



then choosing "Stereo Mix"



But now after doing format for my computer, and installing headset, recording the media from the computer without the microphone cant be done. Only recording using the microphone I can do.

here is some details about the headset if needed...





Notice it have only recording from microphone, it dont have setreo mix.
Anyways I tried using the Realtek menu, but no use


Thats all, any body knows and can help to record media from the pc only?

Thanks for reading...
