1. alsa-lib-1.0.15
- alsa package들은 기본 prefix는 /usr
tar xjf alsa-lib-1.0.15.tar.bz2
cd alsa-lib-1.0.15
./configure --host=arm-generic-linux-gnueabi --build=i386-linux --disable-python

make DESTDIR=/opt/4.2.4-eabi-arm/arm-generic-linux-gnueabi/sys-root install
- alsa library test
cd test

2. alsa-utils
tar xjf alsa-utils-1.0.15.tar.bz2
cd alsa-utils-1.0.15
zcat ../alsa-utils.alsaconf.diff.gz | patch -p1 --verbose --backup --suffix=.orig || exit

3. test......amixer
vi atest
#!/bin/sh
amixer -c 0 sset Master,0 100% unmute
amixer -c 0 sset PCM,0 100% unmute
amixer -c 0 sset 'Master Mono',0 100% unmute
amixer -c 0 sset 'External Amplifier',0 70% unmue
amixer -c 0 sset Headphone,0 70% unmute
amixer -c 0 sset 'Line',0 50% unmute
amixer -c 0 sset 'Video',0 50% mute
이 실행 시크립트는 보드 부팅 후에 실행
4. 후에
aplay g.wav 식으로 실행시키면 됩니다.
