Linux（ubuntu 11.04）でテストするときにJAVAを使用してゲームを作成しますミキサーには1行しかないため、同時にサウンドを再生できません。pulseAudioには-1行があり、これは無制限の行があることを意味するので、そのミキサーを使用しようとしました。しかし、行を開くと、そのエラーが発生しました。

それを修正する方法???

同様のエラーが発生しました。PulseAudio Mixer は、このようにスレッドセーフではないようです。AudioSystem.getSourceDataLine() 呼び出しで外部同期することで解決しました。

Linuxボックス（ミント）でも同様の問題が発生しましたが、これはWindowsでは発生していませんでした。openJDK と JRE から sunJDK と JRE に切り替えると、問題が解決することがわかりました。
