在 Ubuntu 16.04 串流時藍牙崩潰

我的 Ubuntu 16.04 機器上的藍牙驅動程式有問題。當我第一次加載作業系統時，我可以看到藍牙托盤圖標，甚至可以連接到我的藍牙耳機。當我嘗試將某些內容傳輸到耳機時，藍牙崩潰了，除了重新啟動電腦之外，我無法以任何方式重新啟動它。

一些日誌：

兩種不同的耳機都已經發生過這種情況，所以我懷疑這與這些耳機有什麼關係。

藍牙崩潰後，藍牙管理器如下所示：

藍牙管理器

正如您所看到的，即使我啟動了藍牙，它也被禁用了。即使選中了“在功能表列中顯示藍牙狀態”，我也看不到任何東西。

我嘗試重新安裝bluez，但沒有任何變化。

謝謝您的幫忙！

使用藍人小程式 1.23來自 Ubuntu 軟體中心。這將解決您的藍牙崩潰問題
