我施用KDE桌面起动时" 提示 -art消息"
Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device.

声卡配置文件
/etc/modules.conf
Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such device)
The sound server will continue, using the null output device

但用系统设置里的声卡检测可以听到声音.
