I get sound in raspi if force audio jack with omxplayer -o -local test.mp3 but not sounds with service of mrl audiofile and this script:
audiofile = Runtime.createAndStart("audiofile","AudioFile")
audiofile.playfile("/home/pi/Desktop/Mrl/ejemplos/test.mp3")
Audio on Raspberry
I havent tested, but I remember that there is an option in raspi-config to force the sound outut to the 3.5 jack.
