I have a STM32H735-DK and I'm trying to get an audio data from codec WM8994. I programmed the SAI1-A to be SLAVE_RX while SAI1-B is MASTER_TX. I programmed the codec input INL1. Everithing seems to be fine, the DMA fifohalffull and fifofull are generated but audio samples are always zero. can you give me some suggestions?
