Ubuntu 16.04蓝牙耳机-无法将配置文件更改为a2dp_接收器

我有蓝牙耳机索尼WH-1000XM3和Ubuntu 16.04。 我已成功配对设备，但无法将配置文件更改为a2dp。 无论我做了什么，它总是失败，并显示消息“未能将配置文件更改为a2dp_接收器”

我试过：

什么都不管用。 请帮忙

什么样的工作对我来说是一个序列，如下所示：

如果之前已配对，请从蓝牙设备中卸下耳机

在耳机上启用配对模式

打开蓝牙设置并单击添加

此时，您可能已经看到一个名为

LE_WH-1000XM3

的未知类型的设备-不要配对

从设备类型过滤器下拉列表中选择耳机、耳机和其他音频设备（可选）

等待直到出现带耳机类型的

WH-1000XM3

设备

配对

运行Blueman（如果尚未安装，请安装），此时配对的耳机设备名称再次以

LE_WH-

开头

右键单击设备并选择设置

选择音频接收器并单击下一步

只有在这一点上我的耳机告诉我蓝牙连接，耶！设备名称更改为

WH-

，但不带

LE

前缀（尽管您需要关闭并重新打开Blueman以刷新列出的名称，但您仍将在声音设置中看到）

转到“声音设置”，确保所选播放音频设备是耳机（可能不是），并且已选择高保真播放模式（A2DP接收器）（应该已经选择）

很快，当耳机作为

LE_WH-1000XM3

连接时，它们就不工作了。无论是在Blueman还是在sound settings（声音设置）模式下，都不可能更改音频配置文件，实际上在这里它们根本没有列出，即使它们是作为音频设备连接的（从第6点开始的等待）。 当以

WH-1000XM3

连接时，所有音频功能都可用且工作正常（就像Linux上的蓝牙音频一样）。仍然可能需要手动选择所需的音频配置文件，但这只是比较整个耳机设置问题的一个小麻烦

最糟糕的是，一旦我断开耳机并再次连接，无论我做什么，它们都会保持

LE_WH-1000XM3

。因此，我需要重新解开并完成整个过程(╯°□°)╯︵ ┻━┻

额外信息：

LE

代表低能耗蓝牙标准。我猜耳机广告连接有两种模式，常规模式和LE模式。两者都可以连接，但Ubuntu 16.04只支持一种音频。我想知道如何强制执行常规或完全禁用LE模式，因为它似乎总是回退到LE模式，整个配对必须再次进行。

我正在添加另一个答案，因为我不确定这种方式的确定性有多大。此外，这是一个折衷低能耗传输设备连接的解决方案

在我位于

/etc/bluetooth/main.conf的机器上，有以下属性：

# Restricts all controllers to the specified transport. Default value
# is "dual", i.e. both BR/EDR and LE enabled (when supported by the HW).
# Possible values: "dual", "bredr", "le"
#ControllerMode = dual

要禁用低能传输，我已取消注释并设置值：

ControllerMode = bredr

然后我重新启动了蓝牙服务（或重新启动），并在系统蓝牙设置下再次配对了我的索尼WH-1000XM3。从我给出的另一个答案来看，它很快就奏效了，甚至没有使用Blueman或任何其他令人抓狂的技巧。
显然，连接到名为
LE_WH-1000XM3
的设备的问题现在不存在，因为笔记本电脑上的蓝牙主机不监听任何LE设备。我希望这能永远解决这个问题。
我也遇到过同样的情况。最终安装bluez-5.52完美地解决了这个问题。据说以前版本的bluez中的bug导致了这个问题。您只需下载源代码并运行

./configure
make
sudo make install
sudo systemctl daemon-reload
sudo service bluetooth restart

享受吧

参考：
thx！我用我的索尼耳机2年没有a2dp。一个简单的配置解决了它！！！它很有魅力，谢谢！唯一的区别是，在Blueman中，设备名称没有以
LE_
开头（步骤8）。我还没有尝试过断开/连接部分，但只要能够在不必更改配置文件的情况下进行配对就已经很轻松了。
