debian下的alsa
2004, 十二月 29 - 21:54 — hongy19
前段时间重装机器，用的是debian提供的2.6内核，装了alsa-base后发现alsa无法发声，但oss却工作正常。折腾了大半天也没搞明白是怎么回事，无奈之下只好使用oss。今天在版上看到有人讨论，才知道oss不能和alsa共存。而我的问题很可能就是系统在启动的时候预先加载了 oss的驱动。后来用google查了一下，在下面这个网址http://www.sonic.net/~rknop/linux/debian_alsa.html
发现问题果然如此。原来debian中自动侦探硬件的程序discover在检测到声卡后会自动加载oss，只要不让它自动加载就可以了。具体做法就是在/etc/discover.conf中加上一句skip i810_audio 。然后重启就能使用alsa了，不过要注意的是alsa默认是静音，需要自己手动将声音调大。
版上有人说还需要在/etc/hotplug/blacklist中加上i810_audio，我发现不需要这么做。因为安装alsa时，系统在/etc/hotplug/blacklist.d/alsa*中自动添加这些内容。
版上有人说还需要更改/etc/modutils/alsa-base中的相关内容，具体就是将above改为alias。
http://wiki.debian.org.tw/index.php/HardwareIdentification 这个网址讲述了debian中硬件识别的相关知识。

Does Gnome sound mixer work after use alsa ?
After installed Debian testing , you will find the Gnome mixer is not working. But the KDE sound mixer is working fine.
I guest it was becasue OOS does not work with Gnome mixer .

gnome-volume-control is never working
No, for standard debian testing, the gnome-volume-control is never working. I did more than ten installation.
It always have the following error message when I start gnome-volume-control:
"對不起，找不到混音元件或裝置"
I have add my user ID to all groups , still not work.
But Kde mixer working fine with out problem. Mplayer need to select OOS else not work as well.
Actually, all the Gnome sound program on testing is not work.
For example :
gnome-sound-recorder will get:
程式“gnome-sound-recorder”不正常地結束。
rhythmbox will get :
無法產生音效輸出元件；請檢查軟體是否已正確安裝
How can I over come this problem on Gnome ?
Gnome is hopeless compare with KDE on Debian .
I am running Kernel 2.6.8-1 and Gnome 2.8 on Debian testing.

在Gnome上使用mixer
其中一個方法chmod 666 /dev/dsp ， /dev/audio以及/dev/mixer
在Gnome上不能使用mixer
可以試一試 chmod 666 /dev/mixer 來解決這問題
請試一試可不可以解決這問題？
