Guys i need help with audio!

I'm developing this app for ios where the user is supposed to speak into the mic to trigger a sound depending on the velocity of your voice. I have: a 'band filter' array, where i check the velocity of the input; an audio.clip = Microphone.Start where the mic plays the sound it recorded in order to pass the band check and GetSpectrumData so it can make an selection in the frequencies. But when i built it to an iphone device, and i call to play the recorded sound (or the sound the input should trigger), the iphone switches the output to the ear-speaker/phone instead of the regular (lower) speaker.

Does anybody have an idea how to set Microphone/audio.clip output manually to the regular speaker ?

When i solve this i'll post the whole script to the community, i'm planning on making this a complete free asset for all colleagues and fellow developers!
