1.编译环境Doker
2.按照这个介绍搭建自己交叉编译环境
3.源码路径下载路径：
https://www.alsa-project.org/wiki/Main_Page

我这边下载的是
alsa-lib-1.2.6.1
alsa-utils-1.2.6
4.解压，然后交叉编译
5.先编译alsa-lib-1.2.6.1
如下指令：
root@6ad7969cbf4e:/home/3.l-tools/alsa-lib-1.2.6.1# ./configure --prefix=/home/3.l-tools/alsa-lib-1.2.6.1 --host=arm-linux-musleabi
。。。。
。。。。
root@6ad7969cbf4e:/home/3.l-tools/alsa-lib-1.2.6.1# make -j8
。。。
。。。
make install DESTDIR=/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang（我这边自己再创建了一个编译产物安装目录 绝对路径）

如下编译alsa-lib编译产物：
root@6ad7969cbf4e:/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home# cd 3.l-tools/alsa-lib-1.2.6.1/
root@6ad7969cbf4e:/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home/3.l-tools/alsa-lib-1.2.6.1# ls -l
total 16
drwxr-xr-x 2 root root 4096 Feb 26 10:14 bin
drwxr-xr-x 4 root root 4096 Feb 26 10:14 include
drwxr-xr-x 3 root root 4096 Feb 26 10:14 lib
drwxr-xr-x 4 root root 4096 Feb 26 10:14 share
root@6ad7969cbf4e:/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home/3.l-tools/alsa-lib-1.2.6.1# cd bin/

再编译alsa-utils-1.2.6
root@6ad7969cbf4e:/home/3.l-tools/alsa-utils-1.2.6/alsa-utils-1.2.6# ./configure --host=arm-linux-musleabi --prefix=/home/3.l-tools/alsa-utils-1.2.6/alsa-utils-1.2.6 --with-alsa-inc-prefix=/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home/3.l-tools/alsa-lib-1.2.6.1/include --with-alsa-prefix=/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home/3.l-tools/alsa-lib-1.2.6.1/lib --disable-alsamixer --disable-xmlto
checking for a BSD-compatible install… /usr/bin/install -c
checking whether build environment is sane… yes
checking for arm-linux-musleabi-strip… arm-linux-musleabi-strip
checking for a thread-safe mkdir -p… /usr/bin/mkdir -p
checking for gawk… no
checking for mawk… mawk

…
备注：
这里需要注意：
–with-alsa-inc-prefix=/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home/3.l-tools/alsa-lib-1.2.6.1/include --with-alsa-prefix=/home/3.l-tools/alsa-lib-1.2.6.1/alsalibyang/home/3.l-tools/alsa-lib-1.2.6.1/lib
==》这两个路径需要指向刚才alsa-lib编译后的产物路径否则会找不到报错
（如：checking for snd_ctl_open in -lasound… no
configure: error: No linkable libasound was found.
错误）

root@6ad7969cbf4e:/home/3.l-tools/alsa-utils-1.2.6/alsa-utils-1.2.6# make -j8
Making all in include
。。。。
root@6ad7969cbf4e:/home/3.l-tools/alsa-utils-1.2.6/alsa-utils-1.2.6# make install DESTDIR=/home/alsa-util （安装编译产物指定路径）
