mplayer刚开机时由声音，一会儿再打开文件就没有声音了？

请教? Confused Confused Confused Confused Confused Confused Confused Confused

[starskywolf]

没有人来看呢？
今天开机后我又试着打开.mp3竟然一点声音不出了。

哎，“运命唯所系，循环不可寻”。。

信息也太少了!
你开了其它播放器吗?
mplayer是自己编译的吗?

[starskywolf]

不是自己编译的，直接sudo apt-get install mplayer 装的。

输出如下：

［第一步］首先把mplayer卸载
sudo apt-get remove mplayer
［第二步］增加软件源，因为官方源里已经没有mplayer了。
在“应用程序-附件-终端”里输入：
代码:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

sudo gedit /etc/apt/sources.list

#Mirror.lupaworld.com 源
deb http://mirror.lupaworld.com/ubuntu feisty main restricted universe multiverse
deb http://mirror.lupaworld.com/ubuntu feisty-security main restricted universe multiverse
deb http://mirror.lupaworld.com/ubuntu feisty-updates main restricted universe multiverse
deb http://mirror.lupaworld.com/ubuntu feisty-backports main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu/ feisty-proposed main restricted universe multiverse
deb-src http://ubuntu.cn99.com/ubuntu/ feisty-backports main restricted universe multiverse
然后在终端里输入
引用:
sudo apt-get update

sudo apt-get dist-upgrade

然后“系统－系统管理－软件源－第三方软件－Add..”

在文本框里把
deb http://mirror.lupaworld.com/ubuntu feisty main restricted universe multiverse
deb http://mirror.lupaworld.com/ubuntu feisty-security main restricted universe multiverse
deb http://mirror.lupaworld.com/ubuntu feisty-updates main restricted universe multiverse

deb-src http://ubuntu.cn99.com/ubuntu/ feisty-proposed main restricted universe multiverse
deb-src http://ubuntu.cn99.com/ubuntu/ feisty-backports main restricted universe multiverse
烤进去
［第三步］
sudo apt-get install mplayer mozilla-mplayer totem-xine libxine-extracodecs
完成就ok了。


不过就是声音太小。。。。正在想办法。
