PICO-ITX PX-10000g audio out issues

[jeamgt]

Hi,

I have a VIA Pico-itx motherboard and I have the following problem.
SUddenly out of nothing the audio out started to have quite a lot of noise.Although you can hear the music the noise was obvious.I have tried every possible SOFTWARE solution (format PC,re-install the drivers,update drivers) everything and the problem persisted.
Yesterday as I was trying to figure out still what is the reason of the problem,I realized that a capacitor near the audio chip it was blown up for some reason.The capacitor's location is exactly under and horizontal the SATA plug.Is the last capacitor on the edge of the board.
I have taken it out and put another one 100nF but it didn't work. Is there a way to find the exact value of the capacitor because from what is seems this capacitor is part of a digital filter for filtering the audio thus the value should be exact.
Thank you in advance.
