音量有时会达到最大值

  • 772

如果我在 Ubuntu 17.10 上调高音量，它有时会持续到最大。鉴于我只按下了一次按钮，理论上它应该只将音量增加一步。请注意，我只知道音量控制按钮发生的问题，而不是任何其他调整音量的方法，因为我从不使用这些方法。

我该如何解决？

    我做了一些研究，你的问题可能是你的音量按钮改变的音量比他们应该的要多，可能是 100% 而不是 5%。尝试更改您的设置，如下图所示：

    从音量键按下更改命令运行

    gif来自这篇文章：

    如何设置自定义键盘快捷键来控制音量？

    其中谈到更改按下音量按钮时执行的命令。

    如果这不起作用，您可以走粗略的路线并使用一些图标将命令启动器添加到您的工具栏。我制作了这个 gif 来向您展示我的意思：

    在工具栏中添加音量按钮

    命令：

    amixer -D pulse sset Master 5%+
amixer -D pulse sset Master 5%-

    我在 gif 中运行 Ubuntu MATE，它与普通 Ubuntu 略有不同，但它们应该仍然以相同的方式工作，希望这有帮助！
