当我尝试使用 mplayer 播放 .ogg 文件时，什么也没有发生。mplayer 在我的终端中留下以下输出：
jcast@jcast-Galago-Pro:~$ mplayer '/home/jcast/Music/Wade Bowen/The Given/Saturday Night.ogg'

但它几乎立即退出，没有播放任何音频。
我测试过的所有 .ogg 文件都发生这种情况，但我还没有测试音乐库中的每个 .ogg 文件。
使用 ogg123 时，相同的文件确实能产生很好的输出。
如果这种情况发生了一段时间而我却没有注意到，我会感到惊讶（我有 1345 个 .mp3 文件和 1411 个 .ogg 文件），但我不记得最近发生了什么变化而影响了它。
我能找到的相关软件包版本是：
