Hello ,

am trying to play PCM data using lpc4330 + ethernet + lwip(udp), getting noise while playing. am not getting how to avoid the noise.

Here is the call flow,
am using two threads one to receive packets from the network , and second one to transfer(DMA) the buffer to Hardware (Using ping pong buffer).

I am not getting where i am wrong, suggest me.

Thank you
Srinidhi M
