no sound output on linux with java & JMF

I have installed the latest sun java 6 sdk on my ubuntu linux box, but I cannot get any sound out of it. JMF applications like jmstudio are able to open and play files, I am getting no exceptions, but there is no sound.

All other linux sound applications are working fine.

As I am new to java sound: What sound device (ALSA, OSS, /dev/dsp, /dev/audio) is java actually using? Is there a way to change the device used by java (without the need to reprogram the application)?

Thanks for any help

JavaSound supports ALSA on Linux since Java 1.5.You can select the "plughw" devices of ALSA.

Do you get a list of ALSA devices by arecord -l ?
