最近在树莓派3上用自带的蓝牙连接蓝牙音箱，顺便安装Mopidy，费不了不少周折，还是因为树莓派当时没有弄图形界面，主要参考的教程有

https://github.com/davidedg/NAS- ... ez5_PulseAudio5.txt
https://github.com/raspberrypi/linux/issues/2229
https://docs.mopidy.com/en/lates ... ian/#debian-install

步骤如下
# 安装软件
apt-get --no-install-recommends install pulseaudio pulseaudio-module-bluetooth bluez
apt-get bluez-firmware
# 安装播放器
apt-get install mplayer
# 认证用户
adduser root pulse-access
adduser pi pulse-access
adduser mopidy pulse-access  # 这步要在安装完mopidy之后执行
# 修改/etc/dbus-1/system.d/pulseaudio-bluetooth.conf
<busconfig>

  <policy user="pulse">
<allow send_destination="org.bluez"/>
  </policy>

</busconfig>
# 修改/etc/pulse/system.pa
### Bluetooth Support
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover
load-module module-bluetooth-policy
.endif
# 新建/etc/systemd/system/pulseaudio.service
[Unit]
Description=Pulse Audio

[Service]
Type=simple
ExecStart=/usr/bin/pulseaudio --system --disallow-exit --disable-shm --exit-idle-time=-1

[Install]
WantedBy=multi-user.target
# 修改/etc/pulse/daemon.conf
resample-method = speex-fixed-3
# 开启服务
systemctl daemon-reload
systemctl enable pulseaudio.service
systemctl restart bluetooth
systemctl status bluetooth
# 连接蓝牙
bluetoothctl
# 开启蓝牙
power on
agent on
default-agent
scan on
pair xx:xx:xx:xx:xx:xx
trust xx:xx:xx:xx:xx:xx
connect xx:xx:xx:xx:xx:xx
scan off
exit
# 配置pulseaudio
# 修改/etc/pulse/default.pa
load-module module-native-protocol-tcp auth-anonymous=1
# 启动pulseaudio
systemctl start pulseaudio.service
systemctl status pulseaudio.service
# 播放音乐
mplayer -ao pulse file.mp3
# 如果之前用有线测试过可以听到声音，蓝牙不行，可能就是不支持HSF
pactl list
# 显示Card#数字  Profiles里面有headset_head_unit和a2dp_sink，而且 Active Profile为off或者headset_head_unit，那么需要将Active Profile修改成a2dp_sink，命令是
pactl set-card-profile  数字序号 a2dp_sink
之后就可以听到声音了
# 安装mopidy
wget -q -O - https://apt.mopidy.com/mopidy.gpg | sudo apt-key add -
sudo wget -q -O /etc/apt/sources.list.d/mopidy.list https://apt.mopidy.com/jessie.list
sudo apt-get update
sudo apt-get install mopidy
# 把mopidy做成服务
# 修改/etc/mopidy/mopidy.conf
[mpd]
hostname = ::
[http]
hostname = ::
# 做成服务
sudo systemctl enable mopidy
sudo systemctl start mopidy
sudo systemctl status mopidy
# 查看配置
sudo /usr/bin/python /usr/bin/mopidy --config /usr/share/mopidy/conf.d:/etc/mopidy/mopidy.conf config
# 扫描本地媒体
sudo /usr/bin/python /usr/bin/mopidy --config /usr/share/mopidy/conf.d:/etc/mopidy/mopidy.conf local scan
