Lightbulb LG P690 audio problem


Hi! I have an LG P690 with audio problem. Speaker/earpiece is NOT working. Phone was water damaged but I've already cleaned it. I think it's from WM9093 (audio interface), but I can't find it nowhere.
Does anybody know if I can find this IC on another phones?
Thanks!


P.S. - resoldered, reballed the IC but same problem...
