Linux Ubuntu18.04蓝牙没声音 org.bluez.Error.Failed, name org.PulseAudio1 already taken

---

ubuntu 18.04 终端命令行开启/关闭蓝牙

设置面板的蓝牙开关按钮不好用了, 关了就开不了了, 如何手动开启？看这里．

蓝牙没有声音怎么解决？

我的经历，供参考：
蓝牙连上了但是没有声音, 一通折腾, 横冲直撞满头包… 网上说的什么 a2db.py, 反复折腾PulseAudo, Alsamixer 统统不管用. pulseaudio进程杀也杀不死, 死了又复生.
本来觉得已经无望了, 但我怎么会轻易放弃 ?

解决

遇到这个问题，请首先尝试安装Blueman解决，好用！

$ sudo apt-get install blueman

如果到这已经解决了你的问题，后面的内容就不用看了．以下作为记录，仅供参考．不清楚具体哪些操作起到了作用, 所以尽量列出. 有一些是为了展示当前配置.

# 安装pulseaudio-module-bluetooth，还是没有好
$ sudo apt install pulseaudio-module-bluetooth
# pulseaudio -k不起作用．试了改权限
$ sudo chown -R $USER:$USER $HOME/
# 查看进程，准备杀进程，但是其实是杀不死的
$ ps -e | grep pulse
# 输出:
11681 ?        00:00:00 pulseaudio
11686 ?        00:00:00 pulseaudio
# 尝试杀死
$ sudo killall pulseaudio
# 死而复生
$ ps -e | grep pulse
# 输出：
# 11716 ?        00:00:00 pulseaudio
# 11717 tty2     00:00:00 pulseaudio
# 11718 tty2     00:00:00 pulseaudio
# 11720 ?        00:00:00 pulseaudio
# 11721 ?        00:00:00 pulseaudio
# 根据报错　E: [pulseaudio] core-util.c: XDG_RUNTIME_DIR (/run/user/0) 不属于本进程　再次尝试改权限
$ sudo chown -R xxx /run/user/0
# 安装dkms，本机其实已经安装了dkms: 2.3-3ubuntu9.7
$ sudo apt-get install dkms
# 改pulse配置
$ sudo gedit /etc/pulse/default.pa
# 将　load-module module-udev-detect 改为　load-module module-udev-detect tsched=0
# 终极解决：安装blueman！！！
$ sudo apt-get install blueman
# 从启动器打开blueman，设置如下

当Blueman也不好使…

感谢: https://blog.csdn.net/github_36674178/article/details/84715079, 2020.07.20再一次治好ubuntu18.04连不上蓝牙耳机. blueman也不好使
解决过程:

1. 事先重装更新了一些软件:

$ sudo /etc/init.d/bluetooth stop
$ sudo apt-get purge blueman bluez-utils bluez bluetooth
$ sudo apt-get install blueman bluez:i386 bluetooth
$ sudo apt-get install pulseaudio-module-bluetooth* ubuntu-desktop* unity-control-center*
$ sudo /etc/init.d/bluetooth start

2. 然后按照帖子里的说明手动进行配对和连接, 比什么blueman工具都好用

$ bluetoothctl
[bluetooth]# power on
[bluetooth]# show
# 移除
[bluetooth]# remove AE:28:47:A4:16:48
[bluetooth]# list
# 配对
[bluetooth]# pair AE:28:47:A4:16:48
Attempting to pair with AE:28:47:A4:16:48
Failed to pair: org.bluez.Error.ConnectionAttemptFailed
[bluetooth]# pair AE:28:47:A4:16:48
Attempting to pair with AE:28:47:A4:16:48
[CHG] Device AE:28:47:A4:16:48 Connected: yes
# 连接
[bluetooth]# connect AE:28:47:A4:16:48
Attempting to connect to AE:28:47:A4:16:48
Failed to connect: org.bluez.Error.Failed
[CHG] Device AE:28:47:A4:16:48 RSSI: -64
...
[CHG] Device AE:28:47:A4:16:48 RSSI: -76
[bluetooth]# connect AE:28:47:A4:16:48
Attempting to connect to AE:28:47:A4:16:48
[CHG] Device AE:28:47:A4:16:48 RSSI: -64
Failed to connect: org.bluez.Error.Failed
[CHG] Device AE:28:47:A4:16:48 RSSI: -75
...
[CHG] Device AE:28:47:A4:16:48 Connected: yes
[CHG] Device AE:28:47:A4:16:48 Trusted: yes

最后终于配对成功, 去设置-声音里切换输出,就可以听到了.

3. 只有一边有声音
   先将有声音的那只耳机power offer, 然后尝试看能不能连接上没有声音的另一只. 如果连接成功, 再将关闭电源的那只耳机打开.
