晕哥说：

amixer 命令读出通路配置，然后对照wm8960手册设置。
最快的办法还是找一下其他开发板现成的配置

又排查了一下，发现是i2s_dout没有输出，其他的mclk sck，bclk，都有输出，现在也不知道该如何解决。

自制的t113开发板，现状alse已经能识别到了wm8960，

但是无法播放音频，aplay 报错。

经过查询得知说是音频通路没有设置对，
向各位大连求教，如何设置音频通路

我自制的t113开发板，用PD21,PD22的uart1作为串口，用的百问网的tina，现在是boot0和uboot都有输出，到了内核就没有了。

        pinctrl-0 = <&uart2_pins_a>;
        pinctrl-1 = <&uart2_pins_b>;

目前还处在设计电路图设计阶段，看各位开源项目的音频输出都是直接从芯片里出的，想用外挂的i2s音频芯片做输出，不知道行不行。
