声卡死活搞不定！大家快来帮我看看！

myduron

先祝福大家新年好！

我的gentoo是：
$ uname -r
2.4.22-gentoo-r2

是从basic光盘起动，从stage1开始安装的。大概的顺序是stage1、stage2，然后emerge -k xfree，接着emerge gnome(在我破机上编译了13个小时)，配置了一下，进入gnome了。

但是任务栏上的小喇叭是红色的斜叉，单击提示“Couldn't open mixer device /dev/sound/mixer”，我到/dev/sound下面看了，没有mixer设备：

$ ls /dev/sound*
ls: /dev/sound*: 没有那个文件或目录

myduron

然后我打开“多媒体->音量控制”，提示“无法正常运行音量控制，要查看详细的出错信息请单击详细按钮。”。

我单击“详细按钮”，提示“无法打开音频设备/dev/mixer，请确认您拥有打开/dev/mixer设备的权限，并且您在编译内核是加入了声卡支持”。

(我想用lspci命令看看硬件信息，可是没有这个命令)，但我确信我在内核中把声卡编译成模块了，声卡是CMI8738。

接着我把一般用户加入audio组：
# useradd lfx -G audio
useradd: user lfx exists
(命令应该没有错吧？)

重新起动X，甚至机子，故障现象依旧。

myduron

我找到了声卡模块：

# ls /lib/modules/2.4.22-gentoo-r2/kernel/drivers/sound/cmpci.o
/lib/modules/2.4.22-gentoo-r2/kernel/drivers/sound/cmpci.o

试图加载：

# modprobe /lib/modules/2.4.22-gentoo-r2/kernel/drivers/sound/cmpci.o
modprobe: Can't locate module /lib/modules/2.4.22-gentoo-r2/kernel/drivers/sound/cmpci.o

我看了一下已经加载的：

# lsmod

rtc                     7228   0  (autoclean)
3c59x                  27536   1

显然没有加载！

看了论坛一些文章，还是搞不定：(

帮我看看吧，我先谢谢大家！

insmod /lib/modules/2.4.22-gentoo-r2/kernel/drivers/sound/cmpci.o 可以吗？
首先dmesg看看有没有找到声卡的信息
确定内核认出声卡后，在声卡图标上左键单击不返回error说明可以工作，右键单击，去掉"mute（静音）"项:如果前一次声音有错，Gnome不会自动启动声音服务的。

cnyg

nano /etc/modules.d/i386
alias sound-slot-0 cmpci

阿罗

据说一个办法是用hotplug， emerge hotplug, rc-update add hotplug default.

如果不用hotplug，那么：
#echo cmpci >> /etc/modules.autoload.d/kernel-2.4

最后一种办法当然是直接把CMI编译到kernel里面了。

晨想

./snddevices运行没？
alsa-device包里边的。

我用了insmod，可是出错：

怎么回事？
