新版本的openwrt上无法使用

我后来改用sample里的mt7628an_mediatek_linkit-smart-7688.dts的来修改mediatek_linkit-smart-7688的这个配置, 声卡就可以认到了. 但是采到的声音有问题, 录得声音电子噪声很大, 听不到需要录得东西. 我的wm8960的板子是微雪的"WM8960 Audio Board", 是不是还需要修改下dts或者是conf文件?

1. dts的audio-routing部分需要根据实际板子调整，特别是INPUT输入信号，每个板子的配置各不相同，需要的通道加上，不需要的删去，根据原理图配置。
2. 如果是3.5mm接口的麦那么可能是耳机跟插座标准不同，这跟板子选用的标准有关，需要换耳机或者用国标美标转换头。
3. 如果只有一个声道没声音或者噪音，说明电路上输入声道只接了一个，把ALC切换到单声道模式：

   amixer -D sysdefault sset "ALC Function" "Left"
   amixer -D sysdefault sset "Left Input Mixer Boost" on
   amixer -D sysdefault sset "ADC Data Output Select" 'Left Data = Left ADC;  Right Data = Left ADC'

   或者

   amixer -D sysdefault sset "ALC Function" "Right"
   amixer -D sysdefault sset "Right Input Mixer Boost" on
   amixer -D sysdefault sset "ADC Data Output Select" 'Left Data = Right ADC;  Right Data = Right ADC'

按照你说的方法, 去掉了多余的配置,设置了下左声道后可以录制到音频了. 谢谢指导. HLK-7628N这个配置能看出是什么地方配置错误了吗? (实际使用的是这个核心板).

dts中缺少gdma使能，i2s需要gdma才能正常工作

谢谢你的耐心解答, 问题和疑问已经解决.
