linux mint 18.1 音頻問題
我的筆記型電腦上有 linux mint 18.1 和 Windows 10，它們都是全新安裝的。雖然聲音在 Windows 上執行良好。不幸的是，我遇到了一些薄荷問題。
Linux mint 18.1 上的問題：
- 聲音僅從左前揚聲器發出。
- 使用耳機時，揚聲器不斷發出聲音，但耳機聽不到任何聲音。
更新1： 在我發布這個問題之後，我重新啟動了我的筆記型電腦並重新登錄。現在問題變得更糟，根本沒有聲音，既不是來自揚聲器，也不是來自耳機。
更新2：我再次重新啟動。現在兩個揚聲器都可以工作。但是當我插入耳機時，聲音仍然來自揚聲器而不是耳機。我真的不知道這裡發生了什麼。

顯然，將我的核心升級到 4.4 可以解決問題。
