我正在尝试在 RaspberryPi 上播放我的 python 程序中的 midi 声音，但是在尝试初始化流体合成器时，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

有谁知道怎么做？

默认的流体合成器设置显然不适用于 Raspberry Pi。

更改音频驱动程序设置，以便使用alsa而不是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流体合成器，并告诉您的 Python 程序输出到流体合成器的端口。
