内核从2.4.20升级到2.6.7.声卡没有声音了.声卡是作为模块安装的.声卡是黑金2,用的是cs46xx芯片.系统启动时能自动加载声卡模块.用的是KDE

这个显示的就是KDE控制中心->信息->音效 里显示的.

执行KDE里的声卡检测.
型号: CS4614/22/24 [Crystalclear soundfusion audio accelerator]
模块: cs46xx /*这里很奇怪.我声卡模块名是snd-cs46xx.ko,而这里显示是cs46xx*/
播放测试声音出现错误信息:
The cs46xx driver could not be loaded. This soundcard may not be compatible with red hat linux
接着就没听到测试声音.
*****************************************************************
进入KDE时也弹出错误框.其中有"/dev/dsp"这句.
******************************************************************
我用alsaconf,能正确检测到声卡,并改动modprobe.conf,提示说成功配置.可是旧事没声音!!
郁闷啊~~~希望哪位能出手相助,不胜感激. |
