我装的是fedora 8，安装xmms有声音，但是mplayer和audacious均无声音，(mplayer播放视频有图像）。
这是播放是所提示的信息：

使用audacious播放mp3，没有反应！
[root@fedora ~]# audacious
Failed to load plugin (/usr/lib/audacious/Output/liblame.so): /usr/lib/audacious/Output/liblame.so: undefined symbol: ctrlsocket_get_session_id
amidi-plug(amidi-plug.c:amidiplug_init:97): init, read configuration
amidi-plug(i_backend.c:i_backend_load:107): loading backend '/usr/lib/audacious/Input/amidi-plug/ap-alsa.so'
amidi-plug(i_backend.c:i_backend_load:145): backend /usr/lib/audacious/Input/amidi-plug/ap-alsa.so (name 'alsa') successfully loaded

是不是我配制的有问题呢 ？

fedora去掉了mp3支持。

你的机器没有用 ALSA 声卡驱动？

用了alsa声卡驱动！！
可是用xmms能播放声音！！
不过我又这样操作了一下：系统－管理－声卡检测－设置－》选中禁用特定声卡驱动，用mplayer播放就正常了，不过再次播放的时候，又没有声音了，郁闷！！朋友们帮帮忙，我也再琢磨诼磨，等解决了我一定贴出来！！谢谢了 ！！！

终于解决了，呵呵！重新配置声卡,将原有声卡的驱动移出，重新配置就可以了 ！！！
