連接到藍牙但連接失敗：未註冊音頻端點

我用 Windows11 做雙引導 Kali-Linux。所以問題是我想連接我的藍牙揚聲器（JBL GO），但不幸的是我無法連接。我使用 GUI 和 CLI 連接到我的揚聲器。它以前工作得很好。我可以在 Windows 中連接，但不能在我的 Kali 中連接。

這是使用 GUI 的消息：

這是使用 CLI 的消息：

我檢查了藍牙服務：

我已經嘗試過了rfkill，alsa但沒有結果。但是當我嘗試這些命令時：

$ pulseaudio -k
$ pulseaudio -D
$ pulseaudio --start

， 有用。但我無法在pavucontrol. 現在我被困住了：|

這是我的 Kali 版本：

$ uname -a
Linux [my_hostname] 5.14.0-kali2-amd64 #1 SMP Debian 5.14.9-2kali1 (2021-10-04) x86_64 GNU/Linux

藍牙版本：bluetoothctl: 5.61

藍人版：2.2.2-1

我一直在為這個問題打我的頭。自從最新一輪適用於 Kali 的 apt 更新以來，我已經遇到了幾天。在做了一些探勘之後，我發現有一些與 PipeWire 和 pulseaudio 組件相關的包更改（特別是 pipewire-media-session 的刪除、pipewire-pulse 的新安裝和 pipewire 的升級）

我找到了以下文章：https ://wiki.debian.org/BluetoothUser/a2dp#PipeWire

“至少，您需要安裝 libspa-0.2-bluetooth 軟體包，刪除 pulseaudio-module-bluetooth 軟體包（如果之前已安裝），然後重新啟動電腦或重新啟動 PipeWire 服務，否則設備連接將失敗並顯示“協議不可用”。

apt install libspa-0.2-bluetooth && apt purge pulseaudio-module-bluetooth

reboot

我現在有音頻端點，我仍然可以使用 pavucontrol 進行配置。

這是對突然出現的非常醜陋的問題的非常簡單的解決方法。我希望這可以幫助仍然面臨這個問題的人。

額外的

我發現將載入模組功能添加到 @sup2069 的其他解決方案響應中描述的 /etc/pulse/default.pa 似乎已經糾正了我遇到的一個問題，即它不會記住我的音頻配置文件。每次設備重新連接時，我都必須重新配置 pavucontrol 中的預設音頻源。我只是想把那一點資訊扔出去。感謝大家為這個社區做出的所有貢獻！
