Question

尝试将PYO音乐模块用于我的Chromebook（Chroot Dev）（ARM7处理器）（Precise Penguin / ubuntu 12.04）

杓：

>>>import pyo
pyo version 0.7.7 (uses single precision)
>>>pyo.Server(audio='jack').boot()

由于ARM处理器和Precise，必须对依赖项进行一些小的修改：

1] ARM根据Jackd2更改为/ proc / cpuinfo，错误：

FATAL: cannot locate cpu MHz in /proc/cpuinfo

solution?之后错误发生了变化，但知之甚少，知道是否更好。

2] xwPython3.0不适用于Precise：

solution，不应该是一个问题，因为这是UI依赖性正确吗？

现在这就是错误所在：

我设法在Google上找到的任何错误消息的解决方案都没有更改此错误消息。（google用Google搜索其他内容，但你不关心我凌乱的网络历史）

的pulseaudio：

>pulseaudio --start

E: [pulseaudio] main.c: Daemon startup failed.

这可能是主要问题，因为Precise和ChromeOS正在运行sidebyside，这会导致对Deamon的锁定？

>pulseaudio --kill

E: [pulseaudio] main.c: Failed to kill daemon: No such process

>sudo pulseaudio --kill

E: [pulseaudio] core-util.c: Home directory /home/USERNAME not ours. 
E: [pulseaudio] main.c: Failed to kill daemon: Permission denied

sudo权限被拒绝??? PulseAudio在ChromeOS中运行???

jackd：

>jack_control start

Traceback (most recent call last):
  File "/usr/local/bin/jack_control", line 399, in <module>
    main()
  File "/usr/local/bin/jack_control", line 158, in main
    bus = dbus.SessionBus()
  File "/usr/lib/python2.7/dist-packages/dbus/_dbus.py", line 211, in __new__ 
    mainloop=mainloop)
  File "/usr/lib/python2.7/dist-packages/dbus/_dbus.py", line 100, in __new__
    bus = BusConnection.__new__(subclass, bus_type, mainloop=mainloop)

  dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11

这不起作用因为我没有显示器＆＃34;为杰克打开了吗？

Answer 1

Solution 1：将JACK连接到CRAS而不是ALSA，可能是您想要的，除非您想要将ChromeOS与音频断开连接（来自解决方案2的开放链接以获取更多信息）

Solution 2：通过关闭CRAS将ALSA和JACK直接连接到硬件

[Pyo / Jackd / PulseAudio]：杰克错误：无法创建JACK客户端（CromeOS / CROUTON / Precise）
