[原创]无声音之解决

[wjj]

开始安装ubuntu7.10时有声音的，但在一次升级之后却无声音，开始我以为是声卡驱动有问题，但右上角的声音标志却是正常的，所以我排除了声卡驱动的可能性。但始终找不出原因，然后我又打开“系统－－－－首选项－－－－音效”，让他们自己检测，可依然无声，实在无赖。一次偶然的机会我又击右上角的声音标志，发现有好多选项，我就选了“打开音量控制”，“回放”有三个控制，都是最低的，调到中间，还是无声，又选“开关”，发现“headphone”未打勾，打勾。至此，突然有声音了，吓得我一跳，呵呵。。。。。。

我的也是少打一个勾，要在“打开音量控制”－“编辑”－“首选项”中，勾中所有，然后再看有没有没打开的音量控制，我的是“PCM"没打开，打开就好了：）

谢谢LZ了，本来本子的音量就小，装了UBUNTU以后就夸张了。
照着LZ说的看了下，我是把所有的选项都调到了最大，这下子声音终于大了点。
起码还以前在WINDOWS下差不多了，再次感谢。
