Sony WF-L900 LinkBuds 蓝牙耳机未被识别为音频设备

我正在尝试将我的 Sony WF-L900 LinkBuds 连接到装有 Ubuntu 的笔记本电脑作为蓝牙耳机。设备已找到,我可以毫无问题地配对,但是,它并未显示为可供选择的音频设备。Ubuntu 21.10 和即将推出的 ubuntu 22.04 的当前每日版本都出现这种情况。

我一直在检查以下内容:

  • PulseAudio 和所有必需的蓝牙模块均已安装module-bluetooth-discovery
  • 该设备可以配对(通过bluetoothctl

对我来说,该设备似乎没有通过连接时列出的 GATT 服务宣传其音频功能:

为了能够将我的 Sony WF-L900 LinkBuds 用作 Ubuntu 21.10 或更高版本的耳机,我还缺少什么?

答案1

我查看了索尼针对 Windows/Mac 的设置步骤,其中提到使用外壳进行配对(参见源链接)。我在 Linux Mint 上执行了此操作,成功配对(设备显示为 LinkBuds,不连接到 LE_LinkBuds),现在可用作音频输入(麦克风)和输出(系统声音)。我不明白为什么它不能在 Ubuntu 上正常工作。希望这对您有所帮助,因为我也遇到了问题,不明白为什么我遇到的问题和您一样。
