How to programmatically detect if Dolby system is active or not on Android

I have a problem with my android app, when I run on a kindle fire 7" with Dolby active there is a flaw in the sound, but when this option is disabled the problem disappears. I'm using MediaPlayer to play long audio files, i cannot use AudioPool because these are background sounds, i'm already using SoundPool to play effects. There is a way to programmatically detect if Dolby system is active or not on Android application? There is a way to make MediaPlayer accept multichannel? Sorry for my bad english :p
