一步一步地完善我的本本在debian6 squeeze testing wheezy的整体功能，今天又轮到声卡了，其实是驱动都已经安装上了，并且都是最新版，就是
不知道为什么会没声音响。只可以一步一步到查找及解决了。
其实，在列出声卡的时候，看到有两个：
首先查看声卡型号：
leung@debian:~$ lspci -nn | grep Audio
00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03)
01:00.1 Audio device [0403]: ATI Technologies Inc RV710/730 HDMI Audio [Radeon HD 4000 series] [1002:aa38]
leung@debian:~$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xf2600000 irq 49
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xf2110000 irq 50
29 [ThinkPadEC ]: ThinkPad EC - ThinkPad Console Audio Control
ThinkPad Console Audio Control at EC reg 0x30, fw 6JHT69WW-1.290000
查看声卡模块：
leung@debian:~$ lsmod | grep snd
snd_hda_codec_hdmi 26548 1
snd_hda_codec_realtek 272344 1
snd_hda_intel 26182 4

snd_hwdep 13186 1 snd_hda_codec
snd_pcm 63744 4 snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec
snd_seq 45093 0
snd_timer 22917 2 snd_pcm,snd_seq

soundcore 13065 1 snd
snd_page_alloc 13003 2 snd_hda_intel,snd_pcm
leung@debian:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC269 Analog [ALC269 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
从上面的数据可以看出，其实我的系统已经安装了相应的驱动了，一切已就备。
初始化驱动到默认状态
leung@debian:~$ sudo alsactl init
Found hardware: "HDA-Intel" "Realtek ALC269" "HDA:10ec0269,17aa212a,00100004" "0x17aa" "0x20f2"
Hardware is initialized using a generic method
到了这一步，实际上已经可以播放声音了。
停止alsa
leung@debian:~$ sudo /etc/init.d/alsa-utils stop
Shutting down ALSA...done.
leung@debian:~$ sudo alsa force-reload
Terminating processes: 7453.
Unloading ALSA sound driver modules: snd-seq snd-seq-device snd-hda-intel snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-codec snd-hwdep snd-pcm snd-timer snd-page-alloc.
Loading ALSA sound driver modules: snd-seq snd-seq-device snd-hda-intel snd-hda-codec-hdmi snd-hda-codec-realtek snd-hda-codec snd-hwdep snd-pcm snd-timer snd-page-alloc.
启动alsa
leung@debian:~$ sudo /etc/init.d/alsa-utils start
Setting up ALSA...warning: 'alsactl restore' failed with error message 'Found hardware: "HDA-Intel" "Realtek ALC269" "HDA:10ec0269,17aa212a,00100004" "0x17aa" "0x20f2"
Hardware is initialized using a generic method
再查看alsa状态：
leung@debian:~$ sudo cat /dev/sndstat
Sound Driver:3.8.1a-980706 (ALSA v1.0.24 emulation code)

似乎没有加载几个东西：
leung@debian:~$ sudo modprobe snd-pcm-oss
leung@debian:~$ cat /dev/sndstat

再查看：
