Hi,

I am trying to play some audio on my evaluation board,but no luck : I have a buffer that contain slices from various wav files,the buffer located in the external RAM ( if it matters) , and i try to do the following :

EVAL_AUDIO_Init(OUTPUT_DEVICE_AUTO, DEFAULT_VOLMAX, I2S_AudioFreq_44k);
EVAL_AUDIO_Play((uint16_t*)data,audioChunkSize/2); // data is my buffer

Any ideas what maybe i am doing wrong? Thanks

EVAL_AUDIO_Play((uint16_t*)data,audioChunkSize/2); // data is my buffer

execution ,i do enter the callback function : EVAL_AUDIO_TransferComplete_CallBack but no sound whatsoever. Thanks
