成功连接到蓝牙音箱，但我如何在那里引导声音？
我在联想Thinkpad T430笔记本电脑上运行Kubuntu 13.10。
我有蓝牙音箱。
经过大量的故障排除后，我设法连接到扬声器。 bt-device报告：
$ bt-device -l Added devices: [Samsung] W_Audio (5C:F6:DC:88:05:62) $ bt-device -i 5C:F6:DC:88:05:62 [5C:F6:DC:88:05:62] Name: [Samsung] W_Audio Alias: [Samsung] W_Audio [rw] Address: 5C:F6:DC:88:05:62 Icon: audio-card Class: 0x240404 Paired: 1 Trusted: 1 [rw] Blocked: 0 [rw] Connected: 1 UUIDs: [AudioSink, AVRemoteControlTarget, AVRemoteControl]
当我连接到扬声器时，它会发出欢迎声。 当我点击蓝牙管理器中的“音频接收器”（我认为是BlueMon）时，扬声器播放另一个声音，并且蓝牙管理器中会出现“成功”消息。
但蓝牙音频不会出现在设置中的任何位置。 没有选项将声音指向扬声器。 所有声音都来自笔记本电脑扬声器，而蓝牙音箱则是静音。
我安装了pulseaudio和pavucontrol（带有一堆其他脉冲音频和蓝牙相关的软件包）。 输出设备选项卡上的Pavucontrol仅显示主音频设备，但根据网络指南，蓝牙音频应该出现在那里。
所以…一旦我连接了蓝牙音箱，我该怎么指挥声音呢？

要在Pulse Audio中启用蓝牙音频设备发现，我们需要确保我们已经加载了用于pulseaudio的蓝牙套件（ pulseaudio-module-bluetooth） 
应该默认安装）。
然后， 模块 – 蓝牙 – 发现负责将蓝牙音频设备作为接收器（或HSP /电话模式中的源）添加到已知音频设备。
要加载此模块，我们可以发布
pactl load-module module-bluetooth-discover
要在启动pulseaudio声音服务器时始终加载此模块，我们/etc/pulse/default.pa添加到/etc/pulse/default.pa （或我们的自定义基于用户的~/.pulse/default.pa或~/.config/pulse/default.pa resp。，如果此文件存在）：
### Automatically load driver modules for Bluetooth hardware .ifexists module-bluetooth-discover.so load-module module-bluetooth-discover .endif
我有同样的问题。 在https://wiki.archlinux.org/index.php/Bluetooth_headset上我发现了这个：
注意：默认情况下，设备可能已关闭。 在pavucontrol的“配置”选项卡中选择其音频配置文件（OFF，A2DP，HFP）。
选择A2DP后有声音。
