Audio help with Juce

I’ve two pb with sound which might be linked. I have to say that I am on linux.
First, I’ve tried to play sound with the demo and it never works. My soundcard is recognize but when I select a sound a press play, I can’t hear any sound.

Second, I’ve created a application which can load sound (wav) and I wanna play these sounds. I don’t know how it works, and tried in directly sending message to to audiocard ( I write in /dev/dsp ) but it doesn’t work. I’ve noticed that my application seems to make my soundcard busy (I can’pt play sound with another app when it runs.

Can you help me
