jalv 均衡器 (eq10q) 在运行时静音（以及其他错误）

我正在尝试使用声音均衡器在 Debian 杰西.我已经安装了pulseaudio，所以我想到了pulseaudio-equalizer，但它似乎只适用于Debian Stretch。所以我正在尝试eq10q，这让我安装了很多其他库（如 libgtkmm-2.4-dev、lv2-dev、jalv、jack、qjackctl、pulseaudio-module-jack...）。但它仍然没有像我认为的那样工作。如果我跑

jalv.gtk http://eq10q.sourceforge.net/eq/eq10qs

我收到一条很长的错误消息（复制在这个问题的末尾），并且程序停止（任何播放的音乐都会冻结大约一秒钟）。

如果我运行jalv.gtk3而不是jalv.gtk，我会得到一个有点丑陋的界面，但没有声音（视频甚至不会播放歌曲，VLC 播放歌曲，但我没有声音）。关闭 jalv.gtk3 窗口后，声音重新出现，视频开始播放。同样的情况也会发生jalv.gtkmm（唯一的区别是界面漂亮）。

我已经杀死了pulseaudio，启动并停止了jack_control，重新启动了pulseaudio（按照建议这里），重新启动计算机，没有任何作用。

这是我收到的错误消息：

错误消息突然以此结束what():。我想当我移动均衡器中的控件时我应该能够听到声音，对吧？

答案1

Linux 上的声音有点混乱，所以这里有一些背景知识：ALSA 是基本的声音系统，它在内核中提供硬件驱动程序，以及配置和访问它们的方法。最重要的是，还有 Pulseaudio（这是当今大多数发行版默认使用的），它允许更方便和灵活的声源和接收器，包括网络东西，而 Jack 是为低延迟传输而设计的，依赖于单一声音用于计时的卡，用于（半）专业录音和混音任务。

最后两个实在是备择方案，并且不能很好地协同工作。你说你已经安装了Pulseaudio，但是从错误消息来看

JACK server starting in realtime mode with priority 10

等等，jalv正在使用杰克。这行不通。

因此您需要为 Pulseaudio 使用不同的均衡器。我还没有使用过 Pulseaudio 的均衡器（而且我也不想:-），所以我无法给出建议。
