Synchronisation in android

I am using media player to play the sound in the pacman game. whenever it plays the sound then it will give following 开发者_JAVA百科error.

Unable to resync. Signalling end of stream

I want to ask why this type of error comes. Is there any memory problem regarding this and how can i solve this problem. when i do volume up or down then device is restarted whenever sound is played i don't know why.
