对呀层主，你的怎么弄的。我的蓝牙连接没问题，但是只要调用TTS就会导致mopidy运行终止 ...

排错要靠你自己了，这个真的帮不上，相信你一定行的。

现在弄好了前端。把配置里的hostname修改为绝对地址之后，可以正常看到页面跟连接到mpd了。但是只要一开TTS ...

我一直在用的，并不是mopidy，而是个插件，在docker容器中直接调用宿主机的mpalyer来播放。
因为小度DLNA插件升级出错，临时起意才写的这篇。
我可能计划写个篇3--插件版，但会涉及新的问题，又需要写其它的。

错误是由权限导致的failed to open vchiq instance这句在这个链接

如果您收到“ 无法打开vchiq实例 ” 这样的错误，则需要以root用户身份执行操作：

    echo'SUBSYSTEM ==“vchiq”，GROUP =“video”，MODE =“0660”'> /etc/udev/rules.d/10-vchiq-permissions.rules    usermod -a -G video [your_username]

• 或者作为一次性临时解决方案（直到重启）：
  

    chmod a + rw / dev / vchiq

只要一开TTS，状态就变成了failed,

“已按照你的方法配置蓝牙，可以播放；mopidy也配置成功，但只能通过hdmi与3.5mm接口输出，蓝牙音箱链接正常，但蓝牙音箱无法通过mopidy输出，请问还需要什么操作”

由上述你发给我的消息来看，你已基本搞定了mopidy。
建议你用sudo mopidy config 看下配置项[audio]项是否如下
output = autoaudiosink

我的配置确实是output = autoaudiosink，
根据mopidy官方文档这里有
audio/output参数
autoaudiosink alsasink osssink oss4sink pulsesink shout2send gst-inspect-1.0 gst-inspect-1.0 shout2send

应该使用第二种吗？

console_format = %(levelname)-8s %(message)s
debug_format = %(levelname)-8s %(asctime)s [%(process)d:%(threadName)s] %(name)s\n  %(message)s
debug_file = mopidy.log
config_file =

[audio]
mixer = software
mixer_volume = 
output = autoaudiosink
buffer_time =

max_connections = 20
connection_timeout = 60
zeroconf = Mopidy MPD server on $hostname

  listallinfo
