Play sounds during phone call

have you tried having the application open that creates the sounds you want (such as a soundboard) or having your music player (android os, or other) open while the phone call is active? hold-homekey switch to the sound app and play the sound. on my phone the sound comes out of the speaker phone so it should be audible to the microphone if you have the volume set loud enough.

 
apparently there was talk about making such an app. the op on this post asked for one, i didnt read to the very end though so i dont know the result.
