私は、音楽に反応し、それと同期してLEDを点滅させるLEDマトリックス（またはそれらの多く）を表すアプリケーションを構築しようとしています。
私のGUIは次のようになります。
しかし、しばらく曲を再生した後、「LED」を点滅させると、次のようなデッドピクセルが表示されます。
長くプレイすればするほど、デッド ピクセルが増えます。私のログでは、次の例外が発生しています。

私のコードはGITHUBと以下にあります。コンピューターからコンピューターの入力に再生される音楽が好きな場合 (コードから取得できるようにするため)、サウンドカードで「ステレオ ミックス」を有効にする必要があります。その機能がある場合は、それを機能させるために新しいドライバーが必要でした。 . それ以外の場合は、マイクで音楽を再生できます。

Led.javaは、 HansoloのEnzoというライブラリからのものです。ここで見つけることができます。
これは私の最初の Java FX アプリケーションであり、デスクトップ GUI の経験はありません。
誰かが私を正しい方向に向けることができますか?どうすればこれを機能させることができますか?
何かお手伝いできることがあればお知らせください。
