vlc — заикание звука только на некоторых DVD — Xubuntu 22.04

Этот ПК был на Ubuntu около 10 лет. Он никогда не был простым, но работал до тех пор, пока 2 дня назад мы не поставили DVD-видео на паузу в VLC. Когда через несколько часов мы сняли паузу, звук начал постоянно заикаться на высокой громкости, которую нельзя уменьшить ни в VLC, ни в ОС после ее запуска.

Воспроизведение видео/изображений DVD выглядит нормально. Воспроизведение файлов .mp4 в VLC в порядке (поэтому потенциальным обходным путем является копирование DVD-дисков). Звук отлично работает в Firefox, играх Steam и т. д., поэтому я считаю, что проблема связана с воспроизведением vlc dvd.

DVD-диски, с которыми это случилось до сих пор, по общему мнению, имеют некоторую защиту от копирования или шифрование. Я предполагаю, что искажение звука может быть особенностью этого.

Звуковая карта встроена: HDA IntelPlayback представляет собой цифровое стерео IEC958 / SPDIF, которое поступает на AV-ресивер, который в настоящее время настроен на разделение стереосигнала на виртуальный объемный звук 5.1. Если я куплю адаптер, будет возможность воспроизводить звук через видеокарту и вместо этого использовать HDMI.

Звук настроен на звуковой сервер Pulseaudio. Переключение на ALSA, похоже, не влияет на эту проблему.

vlc выдает многочисленные сообщения об ошибках (приведены ниже), большинство из которых я просмотрел, и результаты пока не кажутся особенно полезными.

На данный момент я думаю, что это может быть проблема с размером буфера или с тем, что слишком много других программ открыто относительно буфера. Итак, я смотрю на vlc Advanced Preferences > Input/Codecs. Но если кто-то видел те же ошибки, я был бы очень благодарен за любые указатели.

Этот блок ошибок отражает множественные попытки
