Hello,

I see that the github repo that you link to is a very specific project using a specific module to play sound. Are you using that exact HW? Perhaps your I2S device doesn't have the same settings. Can you please let me know what sound device you are using?

When you say that the sound is not right. Does it resemble the sound it is supposed to make, or is it just noise?

Best regards,

Edvin

There are some bugs in subcontracting, so I'll update it.But the sound is not right. I find EVENTS_TXPTRUPD interrupt.
