C3的I2S ES8311 Example例子没声音

[llinzzi]

关于idf5下i2s_codec的例子I2S ES8311 Example的问题

同样的硬件，我用S3有声音，用C3没有声音。
代码如下，默认代码，只是修改了GPIO。

IDF 5.0和5.1 都测试过。编译和运行都没问题， C3就是没声音。 是IDF的bug么？

1. 用万用表测量 PA 使能引脚是否拉高
2. 使用逻辑分析仪测量 I2S 是否有时钟和数据
3. 若 i2s 正常，可播放正弦波音频测量 es8311 的 dac 输出引脚。并使用 es8311_read_all dump 出所有的寄存器值。与下方寄存器值进行对比
