幫助 Ubuntu 17.10 聲音下降

我合上筆記型電腦的蓋子，當我打開它時，揚聲器或耳機沒有聲音。

如果我啟動 Windows 並重新啟動以啟動 Ubuntu，也會發生這種情況。如果我關閉電腦並打開，然後使用 Ubuntu 啟動，聲音就會正常工作。

我已按照在 askubuntu 和聲音故障排除程序上找到的說明進行操作，但沒有任何效果。請幫忙。 在此輸入影像描述 在此輸入影像描述

讓我知道它是否有效。下面的命令將透過將 snd-hda-intel 模組附加到 /etc/modules 來載入它，您可能需要登出/登入。 echo "snd-hda-intel" | sudo tee -a /etc/modules
