在Gentoo Linux下轻松安装ALSA

ftyh

我编译都可以成功，只是到了启动的时候老是提示找不到声卡，不管我用的是PCI声卡，还是板载声卡都是一样，在LFS下面。

larry

My audio card is
>grep audio /proc/pci
"Intel Corp. 82801BA/BAM AC'97 Audio (rev 2).

How can I do ? are there any tool like sndconfig do it all.

Do I must do
1. compile kernel with
a. sound card support as modue
b. >> intel i8x0  as module
2. restart with new kernel
3. emerge alsa-driver
4. config conf ... then ???

when i do this ,there still haven't sound , How to open the sound ?
my soundcard is via8233
(#grep audio /proc/pci
    Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97 Audio Controller (rev 64).)
so i use the command env ALSA_CARDS='via82xx' emerge alsa-driverto install ALSA.

# amixer set Center 100 unmute
amixer: Unable to find simple control 'Center',0

# amixer set Surround 100 unmute
amixer: Unable to find simple control 'Surround',0
what's wrong?

dancefans

我的是创新128数码板，用env ALSA_CARDS='ens1371' emerge alsa-driver安装成功，
再装alsa-utils之后我运行：
#amixer 出现如下错误提示(内核2.6.0-test7只选了sound modules support )
amixer: Mixer attach default error: No such file or directory

这是为什么？

Debentoo Gao

2.6内核已经集成了ALSA，不需要再安装alsa-drivers了呀

Master

gentoo还没有2.6吧，而且2.6的编译方法有点不一样的。

lordbyorn

I am using gentoo, Kernel is 2.6.0-test8-mm1, I don't have to install alsa, coz kernel has one.

But sound driver can still not be used by two processes.
