20250917在榮品RD-RK3588-MID開發板的Android13系統下使用tinyplay播放wav格式的音頻
2025/9/17 20:37

緣起：板子的音頻/喇叭部分是按照榮品RD-RK3588-MID開發板設計的，但是沒有聲音。
排除了靜音了/聲音過小。
播放網頁視頻/wav音頻都沒有聲音。

后來才定位到是耳機檢測引腳GPIO1C4恒定為低，開機RK3588就認為是耳機模式了！
喇叭肯定沒有聲音了。

RK3588 Android12 拔出耳機后一段時間后系統才檢測到耳機拔出的狀態
https://blog.csdn.net/u011774634/article/details/137873834

原因：
耳機檢測引腳HP_DET的上拉電阻阻值過大，因硬件設計耳機未插入時HP_DET為高電平，耳機插入后為低電平。當把耳機拔出后HP_DET由低電平轉為高電平所需的時間較長（幾十秒），所以系統在耳機拔出后一段時間后才檢測到拔出事件。
