Here is what i want to do:

When in call i want the other person to hear audio output from my pc.The person doesnt need to hear me only the output from pc.

Today i bought an aux cable plugged one end to my pc's headphone jack and plugged other end to my N95.But it didnt work.The person i called didnt hear the music from my pc.

When i plug aux cable it says:

select enhancement

-headphones
-tv out cable
-music stand

i tried all options and everytime i select one it says:

use phone microphone.

So how can i manage this?
