play mp3 with USB via DMA , then UART interrupt Handler miss some data  


sir,
    i am working on a project in which we use stm32f407 discovery board, in which we play audio song with USB using DMA (DMA1 stream7) , and use interrupt handler of UART3 (PB10 and PB11) .
 First we receive audio data and send start DMA ,DMA send the data to CS43l22( audio driver IC connected  in stm32f407 discovery board). simultaneously we send large  data to controller through UART3 (PB10 and PB11). Interrupt handler of UART miss some packet of data
