我的MPLAY可以听歌，但REALPLAY8没有声音，我打开音量控件，出现以下错误：

这是怎么回事？我应该怎么设置，还有我安装的REDHAT有X窗口系统、KDE桌面环境和GNOME桌面环境，我用得是startx来启动的，我不知道这些分别是怎么启动的。

GNOME和KDE都属于X视窗系统,  一般系统安装完后以GNOME为默认的视窗,如果想换成KDE的话就用命令 SWITCHDESK KDE  (注意是小写,命令记不太清了,一般差不多) 同样换成GNOME时就用命令 SWITCHDESK GNOME

我的恰好相反，播放rm文件的时候，声音正常，画面速度却很快，看着很搞笑，放块动作一样，不知道怎么改。
