我有蓝牙耳机Sony 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。 无论我做什么，它都会失败，并显示消息“无法将配置文件更改为 a2dp_sink”。
我已经尝试过：
没有任何作用。 请帮忙。

对我来说什么样的作品是以下顺序：
LE_WH-1000XM3WH-1000XM3类型为耳机的设备
LE_WH-开头
WH-，不带
LE_前缀（尽管您需要关闭并重新打开 Blueman 才能刷新列出的名称，但无论如何您都会在声音设置中看到）
LE_WH-1000XM3
连接时，它们不起作用。无法在 Blueman 或声音设置模式中更改音频配置文件，实际上这里根本没有列出它们，即使它们作为音频设备连接（从第 6 点开始等待）。 当以
WH-1000XM3连接时，所有音频功能都可用并且工作正常（就像 Linux 上的蓝牙音频“正常”一样）。仍然可能需要手动选择所需的音频配置文件，但这只是与整个耳机设置问题相比的一个小烦恼。最糟糕的是，一旦我断开耳机并再次连接它们，无论我做什么，它们都会保持
LE_WH-1000XM3
。所以需要取消配对重新走一遍整个过程(╯°□°)╯︵┻⁄┻额外信息：
LE
代表低功耗蓝牙标准。我猜耳机以两种模式宣传连接：常规模式和 LE 模式。可以同时连接两者，但 Ubuntu 16.04 上仅支持一种音频。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该模式，并且整个配对必须再次完成。
低能耗传输设备连接的解决方法。
在我的机器上/etc/bluetooth/main.conf
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
要禁用低能量传输，我已取消注释并设置值：
ControllerMode = bredr
然后我重新启动蓝牙服务（或重新启动）并在系统蓝牙设置下再次配对我的索尼 WH-1000XM3。它立即起作用，甚至没有使用 Blueman 或我给出的其他答案中的任何其他断颈技巧。 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侦听任何 LE 设备。我希望这能永远解决这个问题。
