Javaアプリケーションは、ユーザーの操作に応答して短い通知音を定期的に再生します。一部のハードウェアでは、3番目または4番目の短いビープ音の後にアプリケーションがロックされます。私たちはpkill java回復しなければなりません。
私たちは約40台のコンピュータにアプリケーションをインストールしました。すべてLinuxを実行します。半分はKubuntu 12.04をインストールし、残りの半分はLinux Mint 11をインストールしました。すべてのLinux Mint 11システムはうまく機能し、Javaアプリケーションは停止しなくてもサウンドを再生します。
最初は（バージョン12.04以降）、すべてのKubuntuマシンが正常に実行されます。
アップデート後、ある時点でKubuntuマシンはサウンドを再生するときにロックを始めました。これは、アプリでサウンド通知オプションをオフにした場合の回避策です。アプリケーションがロックされていません。しかし、ユーザーが望むのはサウンドです。
問題が発見されたとき、私たちはKubuntuシステムでアップデートを実行しなくなりました。
最新のKubuntuシステムでも、すべてのハードウェアにロックの問題はありません。たとえば、Thinkpad X220タブレットでは、アプリケーションのサウンドが正しく機能します。ただし、ThinkPad E430では、アプリケーションでサウンドを有効にするとアプリケーションが停止します。
パターンを検出できません。最新のLinuxが一部のハードウェアで動作を停止するのはなぜですか？以前のLinuxは、私たちが使用しているすべてのハードウェアでうまく動作しますか？
ここに含まれるハードウェアに関する情報があります。もちろん質問：

私は以前LinuxでJavaでサウンドを再生するためにsun.audio.AudioStreamとsun.audio.AudioPlayerを使用して最良の結果を得ました。このコースは「社内」コースなので推奨されませんが、（長年にわたって）他のコースよりも私にとっては効果的でした。この問題が発生するまで。
私の新しい解決策は次のとおりです。Runtime.getRuntime().exec(mediaPlayerCommand + fileName);
メディアプレーヤーの場合は、playOpenSuseまたはmplayerUbuntuを使用できます。ターゲットOSの設定ファイルにコマンドを入れると完璧に動作します。
