HQビデオ（720p以上）を再生するとVLCに問題があります。特定のシーンを見つけようとすると（映画を再生していて30分表示を合わせたいとします）、サウンドは消えます。いつもそうではありませんが、頻繁に発生します。音が出ない場合は、再生中のビデオにのみ音が表示されます。私はParole Media Playerでこのような問題を経験したことがなかったので、VLCにいくつかの設定エラーがあると思いました。何が間違っている可能性があり、どのように解決できるかを知っている人はいますか？
修正する:提案に従ってSkuminder実行しましたが、vlc -vvv my_video.mp4ここで私が得た出力オーディオに関する行が表示されます。

VLCがパルスオーディオ（コマンドラインを介してファイルを再生するvlc --verbose 2 --log-verbose 3 "filename"）を使用している場合は、VLCツール/基本設定/オーディオに移動して他の出力モジュールとデバイスを試すことができます。その後、VLCを再起動するとエラーが表示されることがあります。再起動してください。インターネット上のvlcコマンドの出力でエラールックアップエントリを検索するか、次に検索/レポートできます。お父さんまたはVLCが使用する他のモジュール。
