ge7*_*600 2 ubuntu bluetooth headphones a2dp
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”。
我试过了：
什么都行不通。请帮忙。

什么样的作品对我来说是一个序列如下：
LE_WH-1000XM3未知类型的设备-不要配对！WH-1000XM3与所述类型的设备耳机出现LE_WH-再次以WH-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，但无论如何您都会在声音设置中看到）不久，当耳机连接时，因为LE_WH-1000XM3它们不起作用。无法在声音设置中更改 Blueman 和模式中的音频配置文件，实际上，即使它们作为音频设备连接（第 6 点的等待），它们也根本没有列出。连接时，WH-1000XM3所有音频功能都可用并且工作正常（与 Linux 上的蓝牙音频一样好）。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烦恼。
最糟糕的是，一旦我断开耳机并重新连接它们，LE_WH-1000XM3无论我做什么，它们仍然存在。所以我需要取消配对并再次完成整个过程（？°？°）？？？？？
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，常规和 LE。可以同时连接两者，但 Ubuntu 16.04 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它，并且必须再次完成整个配对。
