CAUSE OF CRAPPY SOUND CHIP, AFTER 1,5-2 YEARS OF USAGE IT DOESNT WORK PROPERLY.(BUT IT WORKS ALWAYS ON JACK MODE,EXTERNAL SPEAKARS WORKS FOR A WHILE DEPENDS ON OVERHEATING OF SOUND CHIP  I TAKES 3-5 MINUTS.)
SOLUTION :
PLACE ON TO THE SOUND CHIP 0.6 mm X 3cm x 10cm RUBBER PLATE. THIS WILL SOLVE THE ISSUE.
I AM NOT MAKING  A JOKE. I AM SERIOUS .
