Audio Buffer Issue with STM32G473VET6 and IMP34DT05TR Mic

[AiROT]

Dear Team,

We are using the STM32G473VET6 microcontroller with the IMP34DT05TR microphone, utilizing the serial audio interface with DMA.

The current buffer size is set to 1000 samples. However, we are encountering an issue where only half of the buffer is being filled, with the remaining portion returning zero values, resulting in incomplete recordings (attached screenshot for reference.)

Could you please advise on how to resolve this?

Best,

AiROT
