alsa的問題

[ifgh]

最近從Debian轉換到Gentoo後發生不少問題
繼上次發問locale中文化的問題後..再發生alsa搞不定
先說明我的環境..
soundcard: intel8x0

Code: Select all

bash-2.05b# lspci | grep Audio
0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801BA/BAM AC'97 Audio (rev 05)

kernel: 2.6.9-r9
alsa-driver: 1.0.7-r4 (/etc/make.conf中加入ALSA_CARDS="intel8x0")

kernel和alsa-driver都裝完後重開啟動alsa發生這樣的錯誤

Code: Select all

bash-2.05b# /etc/init.d/alsasound start
 * Loading ALSA modules...

lsmod的內容為

Code: Select all

bash-2.05b# lsmod

amixer當然不行run

Code: Select all

bash-2.05b# amixer 
amixer: Mixer attach default error: No such file or directory

因為有錯誤..所以想stop alsa再try一次..結果又有這樣的message

Code: Select all

bash-2.05b# /etc/init.d/alsasound stop
 * WARNING:  you are stopping a boot service.
 * Storing ALSA Mixer Levels...

看起來似乎是沒有/dev/snd/seq這device..但我的/etc/devfsd.conf內已有這樣的內容

Code: Select all

LOOKUP          snd          MODLOAD ACTION snd
LOOKUP          dsp          MODLOAD
LOOKUP          mixer        MODLOAD

不知道是不是小弟我那地方忘記設定了!!麻煩各位大大指正一下^^"

你要不要參考一下這個
http://gentoo-wiki.com/HOWTO_ALSA_sound_mixer_aka_dmix

[scsi]

你的機器的 notebook嗎？能說一下型號嗎？
之前用intel8x0好像也沒有聲音
後來後intel8x0m就ok了...
也許你可以用新版的knoppix開機看他抓到哪個型號

[【Palatis】]

alsa-driver 1.0.7 有問題.
我用 1.0.6 好好的, 一升級就抓不到了 = =

我也是 intel8x0 (跟 intel8x0m for modem).

不會吧!!那~~那~~那可以裝回1.0.6嗎?
BTW..我用kernel-2.6.9-r9上的alsa driver同樣有這樣的問題

[【Palatis】]

當然可以. emerge "<=media-sound/alsa-driver-1.0.6" 試試!

[ifgh]

感謝各位大大的解答^^
我安裝alsa 1.0.7似乎成功了(晚上再回家測8))~~原來是沒裝udev
爬文後得知2.4使用devfsd, 2.6使用udev
安裝完udev後使用amixer已經沒那error message
