play_mp3

Hello,

When running the play_mp3 on esp32-lyrat v4.3, I get the following error. I can't hear any audio even though I connected an apple headphones to the PhoneJack.

Hi @SantoshVema1,

Thank you for reporting this error.

I see the same error on ESP32-LyraT v4.3 but can hear the audio using speakers or apple phones through the phone jack without any issues. Have you tried using speakers or another headphones?

The fix for the error itself is in internal review and I hope to get it merged soon.

Hello @krzychb,

Thanks, I was just about to reply saying that I can hear the audio through the headphones but get an error.

Thanks,
Santosh
