if no other problems only one time replacing audio ic will do the job but if you already change it 3 to 4 times then its not in audio ic anymore..try to trace every line in audio ic maybe you have short pins there...check also capacitors near that ic maybe some of them moved when you try to work on the ic and short them..remove all the shield in ic so that you will see all parts what is missing

Try to re-soldered cpu. It may be cpu pseudo soldered.
