audio playback

Hi, we use DM8168, RDK4.0, the audio chip is AIC3101.

I want to receive the aac data from network, and send to aac decode, and then send to playback.

But I found if the network drop one package, the audio  playback is  unnormal.

The console print the message "Underrun occurred" all the time.

How can I avoid it?

Thanks very much.

    Ketty,

    Because of packet drops underrun would happened in DMA. But the further under-runs could be becasue of the prints. Could you please try to remove the print statement and listen to the audio and see whether its the same as before?
