音频开发板 ESP32-S3-Korvo-2 V3.0 使用idf中的i2s_es8311 无法正常播放音乐

[Lewis2001]

我用I2S_es8311这个示例时发现，扬声器有时候能够播放音乐有时候不能
我只修改了示例代码中的io口，和给PA的使能的GPIO
以下是代码

您好，如果在同一固件下，时而播放正常，时而播放失败，首先可以排查一下接线~。
若接线不存在问题并且 PA 可以正常工作，则将正常播放与异常播放时的 es8311 寄存器分别打印出来，提供两种情况的完整 log 进一步 Debug。

[remote_car]

我也碰到过这种现象 。我降低IDF 版本到4.4.2后声音就正常了。你试试

[ESP_William]

大概率还是 8311 寄存器初始化问题，可以将 8311 的寄存器读取出来，然后对比 ADF 默认的寄存器配置，不对的话可以尝试重新写一遍...
