［已解决］关于alsa声卡的设置，耳机有声音，外放没声音

又见 HP

这个问题 lzjx 兄已经解决了,我也是用的他的方法,共享一下:
方法：
vi编辑/etc/modprobe.d/sound

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=laptop enable=1 index=0(加入这条)

在 ubuntu 下,不是改这个文件,而是改 /etc/modprobe.d/alsa-base
同样是加入最后一行.

如果这两个文件都找不到,就找找类似的文件.

关于声卡，看这里：
http://en.opensuse.org/SDB:AudioTroubleshooting
http://en.opensuse.org/SDB:Intel-HDA_sound_problems
一步一步照着检查应该可以解决绝大多数问题

packman的mplayer编译的时候指定realcodec的位置为/usr/lib/RealPlayer/codecs，做个链接到/usr/lib/win32即可，自己重编译mplayer也可以，加上nvidia的vdpau补丁效果不错

声卡问题终于解决了，编辑/etc/modprobe.d/sound如下：

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=hp-m4 enable_msi=1

在google上搜了hp dv5 IDT 92HD71B7X声卡(Intel 82801IB ICH9)的相关信息，添加了model=hp-m4，虽然找了半天没找到hp-m4从那来的，尝试修改了一次，重启后设置了下kmix就OK了，外放、耳机都正常了。
很感谢楼上两位朋友的帮助，现在轻松多了，再把mplayer的问题解决后系统就没什么大问题了。

lz不错呢

我插了耳机它音响和耳机一起响～～

选alsa mixer 把其中一个静音即可

你这个问题比较好解决，
解决方法和楼主的解决方法一样，
加上model项即可，
具体的model请对应你的硬件进行选择，
这里有一份model的对照表：
