pulseaudio：bluez5-util.c：GetManagedObjects（）失败：org.freedesktop.DBus.Error.NoReply：

启动 pulseaudio 时出现错误。如何修复？

启动后我立即执行以下操作：

$sudo fuser -v /dev/snd/*

什么也没有返回。然后：

$ pulseaudio
E: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
^Z
$ sudo fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  joeuser   3178 F.... pulseaudio
/dev/snd/controlC1:  joeuser   3178 F.... pulseaudio
/dev/snd/pcmC0D7p:   joeuser   3178 F...m pulseaudio
/dev/snd/pcmC1D0c:   joeuser   3178 F...m pulseaudio
/dev/snd/pcmC1D0p:   joeuser   3178 F...m pulseaudio

因此，现在 pulseaudio 似乎正在运行，尽管设置中没有出现声音设备：
