Dear,

i am using stm32f746 discovery board. I open Audio_playback_and_record application at STM32Cube_FW_F7_V1.6.0 with IAR complier and modify code with Audio Play for sample 8khz

After  i copy wave file with 8khz sample rate with 16bit resolution,mono to usb and play it at stm32f746 discovery with

Audio_playback_and_record 

application but sound is bad.(this wave file open on computer is OK).

Could you tell me reason why ? stm32f7 discovery can play wave file 8khz ?

Thanks you very much.
