How to make a soundboard be multichannel using FMOD?

Well , i think is correct to make a new topic asking this exactly. I been serching now for over a week how to play differents sounds from different exits in my soundboard. Ill tryed

ofMultiDeviceSoundPlayer :

and ofxMultiSpeakerSoundPlayer

without any succes.

Im using ubuntu. and my external soundboard model is ENMAB-8CM 7.1Channel USB audio box.

Is there any posible way to do it?

Ive made it using OfxMultisoundplayer !!! Drivers update and it was working !
