I downloaded:

alsa-lib-1.1.9.tar.bz2

alsa-utils-1.1.9.tar.bz2

source cross toolchain

$ source /home/myzr/my-work/03_toolchain/fsl-imx-x11-glibc-x86_64-meta-toolcha

Unzip:

$ cd

$ tar xjvf alsa-lib-1.1.9.tar.bz2

$ tar xjvf alsa-utils-1.1.9.tar.bz2

$ mkdir alsa-lib

$ mkdir alsa-utils

Compile and install alsa-lib

$ cd alsa-lib-1.1.9/

$ ./configure --host=arm-poky-linux-gnueabi --prefix=/home/myzr

/alsa-lib --enable-shared --disable-python

$ make

$ make install

Compile and install alsa-utils

$ cd /home/myzr/alsa-utils-1.1.9/

$ ./configure --host=arm-poke-linux-gnueabi --disable-alsamix

er --disable-xmlto CPPFLAGS=-I/home/myzr/alsa-lib/include LDFLAGS=-L/home/myzr/alsa-lib/lib --with-alsa-inc-prefix=/home/myzr/alsa-lib/include --prefix=/home/myzr/alsa-utils

$ make

$ sudo make install

Note: I copied /home/myzr/alsa-lib and /home/myzr/alsa-utils to the home directory of the development board before performing the transplantation operation.

Migrate the files in the /home/myzr/alsa-lib/lib directory to the /usr/lib directory of the development board

# cd alsa-lib/lib/

# cp * /usr/lib/ -r

Move /home/myzr/alsa-lib/share/alsa/alsa.conf to the same directory as the development board

# cd ../share/alsa/

# mkdir /home/myzr/alsa-lib/share/alsa/ -p

# cp alsa.conf /home/myzr/alsa-lib/share/alsa/

Migrate the files in the /home/myzr/alsa-utils/bin directory to the /usr/bin directory of the development board

# cd ../../../alsa-utils/bin/

# cp * /usr/bin/ -r

Migrate the files in the /home/myzr/alsa-utils/sbin directory to the /usr/bin directory of the development board

# cd ../sbin/

# cp * /usr/bin/ -r

test:

Plug the headset into the development board interface and execute:

# aplay ~/alsa-utils/share/sounds/alsa/Front_Center.wav

If the sound of the wav file can be heard normally, the test is successful
