debian中声卡的问题

清华同方锋锐K483装的是debian6.0squeeze,系统装好后有音量图标 ,但是没声音,试着按网上的去弄到现在没结果,看到有个帖子说可以尝试使用“alsactl init”来配置声卡,运行后出现下面的结果
root@debian:/home/xiu# alsactl init
Unknown hardware: "HDA-Intel" "Intel ID 2805" "HDA:11068446,11060000,00100000 HDA:80862805,80860101,00100000" "0x8086" "0x7270"
Hardware is initialized using a guess method

这样的提示是不是因为没安装声卡驱动?
运行lspci后的结果如下
