lspci 信息：
Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02)
可是在安装alsa的时候出现这样的问题：
WARNING: /etc/modprobe.d/linux-sound-base_noOSS line 1: ignoring bad line starting with 'blacklist'
WARNING: /etc/modprobe.d/linux-sound-base_noOSS line 2: ignoring bad line starting with 'blacklist'
WARNING: /etc/modprobe.d/linux-sound-base_noOSS line 3: ignoring bad line starting with 'blacklist'
WARNING: /etc/modprobe.d/linux-sound-base_noOSS line 4: ignoring bad line starting with 'blacklist'
.......一直到58行！！！

不知道这个blacklist是个什么东西？？是脚本程序？还是gcc里面的东东？请高手帮帮忙呀！:comp
