有没有人有 sph0645i2s 麦克风和 esp32-s2 的经验？

如何解决有没有人有 sph0645i2s 麦克风和 esp32-s2 的经验？

我正在尝试使用 ESP32-S2 WROOM（全名：LilyGO TTGO T8 ESP32-S2 WROOM）从 i2s 麦克风（sph0645）读取输入，我得到的只是静音或噪音（如果分配的引脚不在麦克风中）所以我认为连接必须正确。我收到 1 条错误消息，即 E (10715) AUDIO_ELEMENT: [wav] 元素已停止。这个错误信息在 espressif 论坛上找不到，所以我变得有点绝望：P 也很高兴知道这是我关于这个主题的第一篇文章。因此，如果您对如何使这两个组件（i2s 麦克风和 esp32-s2）工作有所了解，请随意！

为了完成故事，这是完整的日志。
