au8820声卡如何安装？

zjracyx

lfs 6.2完成。
机器主板815ep，自带声卡不用，在coms里关了，一块s90声卡，芯片au8820。

编译，安装mpg123，运行，没声音。
问题：内核里不是有声卡驱动里吗，为什么没声音呢？还是要安装ALSA包才行？:mad:

youbest

要装alsa包,还要把音量调节好

zjracyx

哦 ，要装ALSA的。
那内核里的驱动是怎么回事？
装ALSA的步骤我已经找到了，就装。

问题1
root用户运行alsaconf信息：
root@CYX-LFS:~# alsaconf
which: no dialog in (/usr/local/sbin:/usr/local/bin:/bin:/usr/bin:/sbin:/usr/sbin)
which: no whiptail in (/usr/local/sbin:/usr/local/bin:/bin:/usr/bin:/sbin:/usr/sbin)
Error, dialog or whiptail not found.

问题2
root运行alsamixer配置后，可以发声。于是alsactl store储存。
重启，普通用户进入，声卡没 声音，运行alsamixer后正常发声。但每次重启后就没声音了。为什么？:mad:

youbest

1、没装dialog和whiptail
2、看BLFS文档

2、看BLFS文档

就是看BLFS文档作的。起先我是直接编译进内核的，装alsa-driver时说已经install ready了，就重新编译成模块，终于可以编译成功。但余的英文实在不怎么的，3级考试都是没过，真痛恨自己当初不好好学习，看不这些文字。另外问一下，如果直接把声卡驱动编译进内核，是不是就不需要安装alsa-driver了，就可以直接安装alsa-lib后其他东西？:mad:

另外：我的lfs还没装X界面。鉴于英文水平的薄弱，我想在现在用的ubuntu上chroot进lfs 安BLFS。阅读仁兄的文章，
［原创］制作LFS过程中各个阶段恢复工作状态的方法
6.62. Cleaning Up～结束
　　从现在开始一直到制作结束，重新开机后回到工作状态的步骤是：
　　1.重新启动计算机，并从LiveCD启动
　　2.加载分区
　　export LFS=/mnt/lfs
　　mkdir -pv $LFS
　　mount /dev/sda2 $LFS
　　3.加载交换分区（如果不想用交换分区或者没有交换分区可跳过此步骤）
　　swapon /dev/sda1
　　4.加载必要的文件系统
　　mount -vt proc proc $LFS/proc
　　mount -vt sysfs sysfs $LFS/sys
　　5.Chroot到目标系统下
　　chroot "$LFS" /usr/bin/env -i \
　　HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
　　 PATH=/bin:/usr/bin:/sbin:/usr/sbin \
　　/bin/bash --login
　　6.创建/dev下的设备文件
　　mount -nvt tmpfs none /dev
　　/sbin/udevstart
　　mkdir -v /dev/pts
　　mkdir -v /dev/shm
　　mount -vt devpts -o gid=4,mode=620 none /dev/pts
　　mount -vt tmpfs none /dev/shm
　　6.进入编译目录
　　cd /sources
并没有/sbin/udevstart命令啊？我改怎么做？
问题：用livecd当宿主系统和用ubuntu当宿主系统应该没什么区别，t是不是这样的？那/sbin/udevstar又是怎么回事情？
