我正在尝试让 ubuntu 检测并连接到蓝牙发射器。默认情况下，它在 17.04 上的蓝牙设置对话框中不起作用
我已经发现我可以将我的电脑用作 A2DP 接收器/蓝牙扬声器吗？它相当旧了，因为我用的是 17.04，但它在这里不起作用。
没有/etc/bluetooh/audio.conf文件。我尝试Enable=Source在 /etc/bluetooth 中找到的各个文件中添加该行（每次都使用 重新启动蓝牙守护程序systemctl restart bluetooth），但没有任何效果。最后创建一个包含这些行的 /etc/bluetooth/audio.conf 文件。
我看不到蓝牙发射器，显然无法连接
我如何让 ubuntu 充当接收器并连接到我的音频蓝牙发射器？
它是否如其他线程中所述对您有用，这是否意味着它是发射器 TT-BA07 taotronics 的问题？

我有一个 chromecast，但我不知道我的蓝牙适配器最终是否被命名为像我拥有的 chromecast......（哦，这是 chrome 中的一个错误????）
