Question

我正在尝试在RaspberryPi上播放我的python程序中的midi声音，但是当尝试初始化fluidynth时，它会出错：

>>> import fluidsynth
>>> import time
>>> fs = fluidsynth.Synth()
>>> fs.start()

导致以下错误：

Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel

我认为可以通过启动Jack服务器来修复最终消息，但是我无法修复

Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel

错误

任何人都知道怎么做？

Answer 1

默认的fluidynth设置显然不适合Raspberry Pi。

更改audio driver settings，以便使用alsa代替jack。

如果您不知道如何在Python中执行此操作，请从命令行手动启动fluidynth，并告诉您的Python程序输出到fluidsynth的端口。
