耳机仅当拔下并重新插入时才工作

我有一台装有 Ubuntu 18.04 的 Dell XPS 15 9570。

当我插入耳机时,我可以收听音频。一切正常。除了不播放任何音频时会发出刺耳的噪音。

另一个问题是,如果我将耳机插上并重新启动笔记本电脑,耳机似乎无法工作,即我无法听到任何音频。为了能够听到任何声音,我必须拔下耳机并重新插入。

如何解决这些问题?

当我跑步journalctl --follow并插入耳机时,我得到:

然后我戴上耳机并重启。运行后journalctl -b我得到:

答案1

我已经确定了刺耳/嘶嘶声的来源:它出现在跑步后

sudo apt-get install tlp tlp-rdw powertop
sudo tlp start

删除了它。解决了这个问题。

不过,每次重新启动笔记本电脑时,我仍然需要拔下耳机并重新插入。
