我最近安装了 Ubuntu 19.04(计算机之前使用的是 18.04,尝试从该版本升级到 19.04,但出现了一些奇怪的问题。我现在安装的 19.04 是从 USB 磁盘安装的)。
每次我重启电脑,音量都会被设置为 50% - 对于我插入的耳机来说,这个音量太大了。重启后音量不会立即重置。大约 30 秒到 1 分钟后会恢复正常,然后会切换到 50%。
我尝试将以下命令添加到我的 .profile 和启动应用程序中。但都无法阻止它被设置为 50%。
amixer -D pulse sset Master 20%
下面是驱动程序和硬件信息。我的耳机插入卡 0,ALC1150 模拟(我认为。它插入背面的主板 rca 端口)

我恢复到 18.04LTS 并解决了这个问题。不确定 19.04 为什么会这样,但我的电脑上也出现了一些其他奇怪的问题。
