1. 简介
- 专栏总目录
- 本文是基于RK3588平台，音频芯片ES8388调试总结。
- 外接声卡：ES8388
2. 音频ES8388调试
2.1 调试总览，调试步骤分析
- 步骤 ① dts配置
- 步骤 ② 编译烧写，调试
2.2 dts配置
- 系统声音配置：

status = "okay";
compatible = "rockchip,multicodecs-card";
rockchip,card-name = "rockchip-es8388";
hp-det-gpio = <&gpio1 RK_PD5 GPIO_ACTIVE_LOW>;

};
};2.3 编译烧写，调试
- 查看声卡命令：
cat /proc/asound/cards - 将wav文件拷贝到板子上：
adb root
adb remount
adb push C:\adb\test.wav mnt- RK Android 播放音乐 ( RK Android SDK 标配 tiny-alsa 工具 ):
adb shell
cd /mnt
tinyplay ./test.wav -D 0 -d 0- RK Android 录音：
tinycap /sdcard/test.wav
播放录音
cd /sdcard
tinyplay ./test.wav -D 0 -d 0- RK Linux 播放音乐 （ RK Linux SDK 标配 alsa-utils 工具 ）
aplay test.wav或者
aplay -Dplughw:0,0 test.wav
aplay -Dplughw:1,0 test.wav
aplay -Dplughw:2,0 test.wav
-Dplughw:x 表示指定第几个声卡或者
aplay -D plughw:CARD=rockchipes8388 test.wav- RK Linux 录音
arecord -D hw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav test.wav
-d 10表示录制10秒声音，test.wav是保存的文件名称
-D hw:x 表示指定第几个声卡
-r 指定采样率，-f 指定每个采样点的位数--样本大小
