[求助】alsa加载声卡模块时出错

时间：2009-02-16

来源：互联网

我初次安装gentoo，安装alsa时出错了。（内核2.6.28）
第一次把驱动build in在内核里，结果alsaconf找不到声卡，但是alsamixer识别得出，并且可以放出音乐。听说把驱动编译成模块较好，于是就重新编译内核，安装成模块。
在/etc/modules.d/autoload.d/kernel-2.6里添加了snd-hda-intel。rc-update add alsasound boot.之后开机之后提示alsa那一块出错了。登陆后lsmod没有显示有模块加载。

dmesg如下：
[ 9.741283] snd: module is already loaded
[ 9.755426] snd_mixer_oss: exports duplicate symbol snd_mixer_oss_ioctl_card (owned by kernel)
[ 9.762358] snd: module is already loaded
[ 9.763820] snd_mixer_oss: exports duplicate symbol snd_mixer_oss_ioctl_card (owned by kernel)
[ 9.764712] snd_page_alloc: exports duplicate symbol snd_free_pages (owned by kernel)
[ 9.765064] snd_timer: module is already loaded
[ 9.765607] snd_pcm: module is already loaded

[ 9.778030] snd: module is already loaded
[ 9.787368] snd_seq_device: exports duplicate symbol snd_seq_autoload_unlock (owned by kernel)
[ 9.787739] snd_timer: module is already loaded
[ 9.789215] snd_seq: module is already loaded
[ 13.204119] ADDRCONF(NETDEV_UP): eth0: link is not ready

[ 13.205615] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 23.750019] eth0: no IPv6 routers present

于是modprobe snd-hda-intel,提示如下：
WARNING: Error inserting snd_page_allocc (/lib/modules/2.6.28-gentoo-r1/kernel/sound/core/snd-page-alloc.ko): Invalid module format
WARNING: Error inserting snd (/lib/modules/2.6.28-gentoo-r1/kernel/sound/core/snd.o): Invalid module argument

FATAL: Error inserting snd_hda_intel (/lib/modules/2.6.28-gentoo-r1/kernel/sound/core/snd-ha-intel .ko): Invalid module argument

dmesg如下：
[ 69.490062] snd_page_alloc: exports duplicate symbol snd_free_pages (owned by kernel)
[ 69.490516] snd: module is already loaded
[ 69.490856] snd_timer: module is already loaded
[ 69.491343] snd_pcm: module is already loaded
[ 69.492930] snd_hda_intel: module is already loaded

但是alsaconf，alsamixer之后可以用mpg123放音乐。

请问各位，这是什么原因啊，是不是2.6.28内核的原因？

在/etc/modules.d/autoload.d/kernel-2.6里snd-hda-intel注释掉试一下
怀疑在这之前就已经加载了模块

出错信息是不是与下面差不多呀？

代码:

# /etc/init.d/alsasound start
* Loading ALSA modules...
* Loading: kernelsnd-mixer-oss...
FATAL: Module kernelsnd_mixer_oss not found. [ !! ]
* Loading: kernelsnd-pcm-oss...
FATAL: Module kernelsnd_pcm_oss not found. [ !! ]
* Loading: kernelsnd-seq-oss...
FATAL: Module kernelsnd_seq_oss not found. [ !! ]
* Loading: kernelsnd-seq...
FATAL: Module kernelsnd_seq not found. [ ok ]

如果是这样，就要打补丁了：

这样的错误提示：

WARNING: Error inserting snd_page_allocc (/lib/modules/2.6.28-gentoo-r1/kernel/sound/core/snd-page-alloc.ko): Invalid module format
WARNING: Error inserting snd (/lib/modules/2.6.28-gentoo-r1/kernel/sound/core/snd.o): Invalid module argument

FATAL: Error inserting snd_hda_intel (/lib/modules/2.6.28-gentoo-r1/kernel/sound/core/snd-ha-intel .ko): Invalid module argument

我现在用2.6.27的内核，没有错误提示了。。。

应该是同时安装了内核驱动和外部驱动，请选择其中一种就行了。
检查方法：
内核驱动：你是否在内核里面选择了你的声卡型号。
外部驱动：emerge -search alsa-driver 看看是否已经安装。

请选择其中一种就行了。
