Description

I put the .wav file in flash, then read it using LittleFS, and played the file using i2s's playWAV.
It prompted esp32-hal-periman.c:122] perimanSetPinBus(): Invalid pin: 255, using max98357A.

The audio files are placed in the compressed package
audio.zip

The same situation occurs when playing MP3

Hi @lmabbe-lm, is the WAV or MP3 played? Can you try to comment the speaker1.end(); in your code and post the debug log again? Thank you

[lmabbe-lm]

你好@lmabbe-lm，播放的是 WAV 还是 MP3？你能尝试在代码中注释掉speaker1.end();并再次发布调试日志吗？谢谢

After commenting, it can work normally now. Thank you for your answer. May I ask about the timing of using end()? The role of end().
By the way, what happens when the sound is too low and how can I adjust it. thank you

[P-R-O-C-H-Y]

You should call the end() if you no longer want to play anything and free resources + the i2s peripheral.
I have opened a fix for the error that you were getting.

About the volume, we have no software control implemented in the I2S library.
You may need to control the volume on HW layer by using some amplifier.

[lmabbe-lm]

end()如果您不想再播放任何内容，请拨打电话并释放资源 + i2s 外围设备。 我已经为您遇到的错误打开了修复程序。

关于音量，我们没有在 I2S 库中实现软件控制。 您可能需要使用一些放大器在硬件层上控制音量。

OK, thanks
