1) 开发板上有板载 MIC，位置如下所示：

2) 运行 test_record.sh main 命令会通过板载 MIC 录制一段音频，然后播放到 HDMI 和耳机。

orangepi@orangepi:~$ test_record.sh main Start recording: /tmp/test.wav Recording WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Start playing Playing WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Playing WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

3) 除了板载 MIC，我们还可以通过带 MIC 功能的耳机来录制音频。将带 MIC 功能的耳机插入开发板后，运行 test_record.sh headset 命令会通过耳机录制一段音频，然后播放到 HDMI 和耳机。

orangepi@orangepi:~$ test_record.sh headset Start recording: /tmp/test.wav Recording WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Start playing Playing WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Playing WAVE '/tmp/test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
