我正在尝试使用Overtone但是当我启动它时，我收到有关jackd的错误。

这是一个几乎全新安装的Ubuntu 14.04，我安装了leiningen并试图安装这里建议的内容：https://github.com/overtone/overtone/wiki/Installing-and-starting-jack

他们建议运行的jackd命令也不起作用，也会出错。

Answer 1

这是因为您的插孔配置未正确设置在您的声卡上。尝试下载QJackCtl（一个用于jackd的GUI）并在午餐Overtone之前启动千斤顶。如果您使用QJackCtl成功启动千斤顶，那么泛音应该正常启动。在Ubuntu中，您应该可以使用apt-get install qjack *

找到它

请注意，如果您不确定如何配置线路输入（例如麦克风），则可能需要选择播放。
