把这个注释掉就好了

@waterworld 已经解决了，电平配置错误了，感谢各位！

请教一下，gpio-key驱动，读取事件的时候一直在上报，按键没有按下，这是怎么回事？：

现在有个疑问，在设备树中IO口配置如下，理论上是打开内部上拉的呀，但是无效：

@yixintai 好的，已经可以了，感谢各位

arecord -D hw:audiocodec -f S32_LE -r 16000 -c 1 -d10 /tmp/test32.wav
你好，使用一个通道，录到的全是噪声，PC上也播放不了。

晕哥，你好，使用下面指令录制音频文件在电脑上可以播放，但是板子上播放不了，这是什么原因？

arecord -D hw:audiocodec -f S32_LE -r 16000 -c 3 -d10 /tmp/test32.wav

@whycan 播放wav格式的音乐正常播放，录制的音频文件放到电脑上也没有声音

这是启动log:
