在带有 Pipewire 和 WirePlumber 的 Debian 上，我得到，
[MX Ergo]# connect 8C:91:09:55:1A:CA
Attempting to connect to 8C:91:09:55:1A:CA
Failed to connect: org.bluez.Error.Failed br-connection-profile-unavailable
以前在 PulseAudio 中这是有效的。我看到这将是所有设备，

答案1
发生此错误的原因可能是libspa-0.2-bluetooth软件包未安装。
如果是这种情况，您可能需要安装pipewire-audio该软件包“依赖于一组推荐的用于标准音频桌面使用的 pipewire 软件包”，包括libspa-0.2-bluetooth。
