I managed to get a sound by doing :
        if ( nas ) {
                AuStatus ret;
                AuEvent ev;
                AuFixedPoint volume, AuFixedPointFromFraction(100,100);
               //sync_play_cb is a dummy callback and does not do anything
                if ( AuSoundPlayFromFile( nas, soundName, AuNone, volume,
                               sync_play_cb, NULL, &autoflowid, NULL,
NULL, &ret) == NULL )
                    fprintf(stderr, "Can't play audio.\n");

               AuNextEvent(nas, AuTrue, &ev);
              AuDispatchEvent(nas, &ev);
       }

Is it the correct way to play a file asynchronously ? I don't want to
have AuNextEvent waiting for an incoming event.
