私はシンクライアントにインストールされているLinux Mint 19.1を使用しています。しかし、カーネル4.15に問題があり（イーサネットポートに接続されているVoIPが機能しない）、問題を解決するためにカーネルを4.4に変更しました。カーネルを変更すると、HDMIオーディオに障害が発生します。私はこの問題を解決するためにいくつかの方法を試しましたが、それはできません。
インストールしました勉強コントロールコンピュータをより奇妙な点を発見しました。 4.15 カーネルの場合はステータスポートが接続されていますが、カーネル 4.4 の場合はステータスポートが切断されています。詳細は次のとおりです。
