在虚拟模式下运行 jack 不会从 Internet DJ 控制台发出任何音频，但从服务器播放的流可以正常工作。您可以在http://myradiostream.com/olpr
该服务器是一个shoutcast服务器，具有以下设置。
Server address: s18.myradiostream.com
Port: 4362
Bitrate: 128kbps
在终端运行 jack 的输出如下所示...

问题是，您也可以像这样运行 jack，并在计算机上获得音频，但在流中却听不到。当您这样运行它时，计算机上的音频非常清晰。然而，流显示了歌曲名称和在线状态，但您什么也听不到。

请帮我解决这个问题。过去一周我一直在仔细阅读手册，最终我意识到自己并不是一个音频工程师。
提前感谢 Ubuntu 天才！:)
另外，附录。重新启动计算机会导致 IDJC 音频出现噼啪声，并且流中没有声音。
更新
我安装了 Patchage 来查看我的连接，看起来我路由到扬声器一切正常，但流无法接收音频。这就像流的音量被调低了，但其余信息流传输得非常好。人们可以看到我的 DJ 名称以及有关曲目和在线状态的信息。他们什么也听不到！
为了将音频传送到流中我缺少什么？
我本来想发布图片，但这个网站阻止我这样做，理由是我的声誉点数太低或类似的原因。
更新2
我刚刚在一台 32 位塔式机上安装了所有这些，但它以完全相同的方式失败了。
更新 3
我让它在流中工作了！
问题是我不太清楚我是怎么做到的。我安装了一堆 Ubuntu Studio 元包，然后从我的系统中清除了所有内容并重新安装了 IDJC。它现在可以正常工作了，所以我会接受它。如果其他人看到这个并需要类似的帮助，请继续努力，你会做得很好！我保证！

要将 IDJC 输出路由到扬声器，请使用 QjackCtl 等工具将 IDJC 输出端口连接到 ALSA 扬声器端口：
