Not transmitting I2S audio on NUCLEO-H753ZI (board broken?)

[s319189]

As the title suggests, I see in debug mode that audio is captured from I2S_RX, but it is not transmitted on the transducer (I cannot hear any audio coming from I2S_RX with my hear). And the problem is that with the same hardware wiring it works on the other boards (including H7S3L8), but not on this specifically. I’ve tried to place dma buffer in RAM D2 and I’ve disabled D cache,  ut it does not solve anything. Is the board I’ve ordered broken? I upload the code below

Hello ​@s319189;

 

Could you please check the used pin. For that I recommend you to look at UM2407 and verify the I2S pins, jumper and solder bridge.

 

Thank you.
