Hi, greetings to all and blessings. I'm just searching something to make this I gonna explain to you possible. I just want on a call, talk (from computer or other mic) and put sounds during the call from the computer. Meaning that my computers out sound will be the microphone from my call. Sorry for my bad English, I just want to talk from my computer or whichever mic but at the same time, put some music during the call. And the most important thing, hear the person without feedback or something :S

Its like a radio station, when you call, you can hear music and a person during the call
