我的 xubuntu 14.04 的声音出现了一些严重问题。每隔 2-4 秒,我的声音就会发出一些噪音。右上角的音量栏不停地显示音量变为 100%,并在 0.5 秒内恢复到原来的水平。我的 pavucontrol 图标消失了,如果我从终端启动它,它会显示“模拟耳机(拔出)”0.5 秒,然后立即变回耳机,再变回扬声器等等。当我卸载 pulse 时,alsa 会发出一些奇怪的噼啪声。
我目前所做的:
- 卸载 Pulse
- 重新安装Pulse
- 将 Alsa 的“自动静音”更改为“禁用”
- 买了新的音箱
- 拔掉我的麦克风和所有声音设备
- 启动实时系统(无错误)
- 在 google 上搜索了好几天..
提前致谢!
