My board is based on Keil_MCB_4357 , it has a UDA1380 audio codec,
LPCOpen sample for I2S peripheral samples the audio from Mic or Line-in and then sends the sampled data (32 bit) to I2S, this sample is fine on my board.

but I want to open a file, read bytes one by one and send bytes to the uda1380 codec, I can only hear some noise when I send the buffer to UDA1380,

any comment or sample for doing this is appreciated.
