を取得Ubuntuの11.04

Name: PulseAudio Mixer 
Vendor: IcedTea 
Version: 0.02 
Description: the ear-candy mixer 

にミキサーを発見されましたJAVA Linux（ubuntu 11.04）でテストすると、ミキサーには1行しかないので、同時にサウンドを再生することはできません。私はnetからpulseAudioに-1行あります。つまり、そのミキサーを使用しようとしたので無制限の回線があることを意味します。しかし、私はラインを開くときに私はそのエラーを持っています。

これを修正する方法は？

Answer 1

同様のエラーが発生しました。このように、PulseAudioミキサーはスレッドセーフではないようです。 AudioSystem.getSourceDataLine（）呼び出しを外部で同期させることで解決しました。

Answer 2

Windowsで起こっていなかった私のLinuxボックス（ミント）にも同様の問題がありました。私はopenJDKとJREからsunJDKとJREへの切り替えが私の問題を解決したことを知りました。
