[己解決]ALSA:No Such Device /dev/dsp /dev/mixer /dev/midi

[Sanada Yukimura]

請教各位，我按照手冊文件安裝ALSA，我emerge alsa-driver alsa-utils alsa-oss 之後,使用alsaconf 進行設定,在設定完成後
ALSA 回應如下:

而且我發現我既無 /dev/dsp /dev/mixer /dev/midi
但是有 /dev/dsp1 /dev/dsp2 /dev/dsp3
mixer 和 midi 同上
我有找過Gentoo Forums 的相關文章,但是都得不到結果!
我是使用alsa-package 的方式,而不是編入核心,是採模組式

lspci -v 得到如下
00:0e.0 Multimedia audio controller: Ensoniq 5880 AudioPCI (rev 02)
Subsystem: Giga-byte Technology 5880 AudioPCI On Motherboard 6OXET
Flags: bus master, slow devsel, latency 64, IRQ 9
I/O ports at d800
Capabilities: [dc] Power Management version 1

我是採用ens-1371
試問?除了編入核心外,還有其它方法嗎?
還有 udev 中的規則設定有須要修改嗎?
我發現一個現象,若是udev 有發現該硬體元件,會產生一個連結的設備
如 /dev/video->/dev/video0


[自問自答]
之前在編譯核心時是kernel-2.6.15-r1 是採用genkernel all 來編譯的
沒想到,居然沒把alsa 給編進去
所以又下載了kernel-2.6.16-r3 順便更新,
但這次得採用genkernel --menuconfig all
記得加 --menuconfig 參數,且得檢查 Device 中的alsa 是否有編入喔
