Using speaker while recording video with audio

I have attached a speaker at the Aout pin on the ameba82 board. and the “PlayMP3” example is working and i am able to play the audio.now I want to play a sound like “recording start” and “recording stop” whenever i start and stop the video recording using a button press. I am recording video with audio. It works when i only record video without audio but when i record video with audio, I receive the following error.
