我遇到了媒体播放断断续续的情况，就像在播放 CD 时敲击旧 CD 播放器一样。音频可能会跳回大约 200-500 毫秒。这种行为发生的频率从几秒到几分钟不等。我在使用 Firefox 中的 YouTube 视频播放、VLC MP4 播放或 mplayer WAV 播放等源时遇到过这种行为。有趣的是，在 Vivaldi 浏览器中播放任何媒体时，这种情况不会发生。它也发生在维瓦尔第，但有一个 40 分钟的阶段没有发生。我还观察到，发生错误时 CPU 负载略有下降。我正在使用主板的模拟音频输出。使用相同硬件的 Windows 上的播放效果很好。
这是有关我的设置的一些信息。自从我最初问这个问题以来，我从 Fedora 切换到了 openSUSE，但问题仍然存在。在我当前和之前的设置中，我使用 KDE 桌面，目前是 openSUSE 存储库 5.2 中的最新稳定版本。如果您需要更多信息，请留下评论。
