使用MP3播放器时，两种音频均可正常工作。第一个有效的音频只是我的MP3播放器中的一首随机歌曲。第二个文件是在一个音乐工作室录制的，该音乐工作室使用多个频道进行现场播放

有什么我遗漏的吗？

您能提供文件以便我们可以尝试复制问题吗？我将尝试在某个地方主持。只是为了明确是谁试图结束此问题。.oma文件不是盗版文件，该文件中记录的音频是我10年前旧乐队的个人音频，这是我试图检索的最后一个内存。@LordNeckbeard，如下链接：DRM是OpenMG格式的中心“功能”。如果你没有最初创建文件的计算机，恐怕你运气不好。顺便说一句，如果你是一个用户，在我的例子中，通过在评论中添加@AkselA，用户会立即收到你的回复。
