怎么办?

答案1

我发现安装

gnome-media pulseaudio 

似乎解决了这个问题

答案2

我使用的是 Ubuntu 12.04 64 位,最近安装了 XFCE-4 桌面。当我第一次登录 xfce-4 时,我注意到根本没有声音(Rythmbox、游戏等)。而且我没有找到任何可以调整声音的图标。

这是我解决问题的方法:

1)转到应用程序菜单>声音和视频>混音器。

2) 在声卡选项菜单中,选择播放:内置音频模拟立体声(PulseAudio Mixer)。

3) 播放窗口可能为空。单击“选择控件...”,启用/选中主控,然后关闭。

4)取消音量条下方的声音图标的静音。

我猜你需要检查你使用的是 PulseAudio 还是 Alsa 驱动程序。这不会改变你需要在 Mixer 中的“播放:音频立体声”中取消选中静音图标的事实。

我希望这能有所帮助:-)

PS:我是Linux方面的新手,如果我说错了什么,请纠正我。
