13.04 罗技蓝牙音箱适配器配对但没有混音器输出

13.04 罗技蓝牙音箱适配器配对但没有混音器输出

我必须改变

[General]
Enable = Socket

在 /etc/bluetooth/audio.conf 中将其配对。但是现在它们配对了,我在 pavucontrol 中没有得到输出。

我该怎么做才能让它工作?

在 pavucontrol 中,我有“(34)Logitech Adapter”。如果我将配置文件从“关闭”更改为“高保真播放 (A2DP)”,那么我会从 pulseaudio 收到以下消息:

W: [pulseaudio] module-bluetooth-device.c: Profile has no transport

有趣的是,通过 blueman 断开设备会导致 pulseaudio 崩溃:

E: [pulseaudio] hook-list.c: Assertion 'hook->n_firing == 0' failed at pulsecore/hook-list.c:51, function pa_hook_done(). Aborting.

升级到 13.10 也没有解决问题。似乎与 bluez 和 pulseaudio 以及某些硬件存在一些不兼容问题...

我很长时间都在寻找解决方案,最后那个链接帮助了我: http://ubuntuforums.org/showthread.php?t=2246613

Ubuntu 14.04 音频接收器问题至 Logitech 无线适配器

你好,jcmoriaud。我最近遇到了这个问题,因为我买了一个蓝牙扬声器并试图用我的笔记本电脑连接到它。它一直显示“连接失败:流设置失败”。我最终想出了如何让它像这样工作。您需要安装 pulseaudio,您可以在 Synaptic 软件包管理器中通过在搜索栏中输入 pulseaudio 来检查。如果尚未安装,您可以从那里安装它。接下来,您需要安装 pavucontrol,可以在 Synaptic 软件包管理器中安装,也可以在终端中运行它。代码:sudo apt-get install pavucontrol 这是不幸的部分。每次启动时,您都需要在任何蓝牙设备尝试连接之前在终端中运行此命令。代码:pactl load-module module-bluetooth-discover 您现在可以进入蓝牙管理器并告诉它作为 A2DP 音频接收器连接到设备。现在,最后,如果您进入 PulseAudio 音量控制,在“播放”选项卡上,您可以选择通过蓝牙设备发送音频的选项。祝你好运。”

我将其与 Blueman (GTK+ 蓝牙管理器) 一起使用

答案2

我也遇到过类似的问题。我设法通过从问题开头引用的 /etc/bluetooth/audio.conf 中的启用行中删除 Socket 来使其正常工作。接下来,从命令行运行:

pactl load-module module-bluetooth-discover

然后您应该能够正确连接到蓝牙音频设备。

答案3

在我清洁键盘之后,我的立体声音响系统就不再有声音了,我通过 Logitech Audio 蓝牙适配器的克隆版连接到了我的 Ubuntu 笔记本电脑。

经过大量浪费时间的研究后,我找到了这个简单的解决方案:

  1. 确保有连接。播放音乐时,你可以看到 MB 传输上升(=数据传输)。
  2. 在终端窗口中,运行 pavucontrol
  3. 在 pavucontrol 中转到“音频输出”选项卡(我使用的是荷兰语版本,所以不确定它的英语名称是什么)。
  4. 寻找你的蓝牙适配器。我的适配器名为“Esinkin BT Adapter”。
  5. 就我而言,“Esinkin BT Adapter”已静音。取消静音按钮后,音乐通过扬声器传出,加载且清晰。是的!
