14 音频测试
14.1 播放音频# aplay /unit_tests/audio8k16S.wav
Playing WAVE '/unit_tests/audio8k16S.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Stereo
14.2 音频录音录音 # arecord -d 5 -f S16_LE -t wav foobar.wav 播放录音 # aplay foobar.wav
15 显示屏(选配)测试特别说明： 当U-Boot 版本u-boot-2016.03 svn315及以上 内核 版本 linux-3.0.35 svn31及以上 linux-3.14.52 svn369及以上 linux-3.14.52 svn368及以上 烧录工具 MfgTool-MYIMX6A9-L* svn181及以上 请参考《MY-IMX6-A9系列：显示功能测试》进行测试 一般情况下则按照如下方法测试 在系统启动过程中，可以看到 Linux 小企鹅和 OpenEmbedded 启动画面。
