Sound not working at all! Help please!

Hi, for some reason there is no sound on an iPhone 6 Plus that I repaired. I have switched the logic board onto one that does have sound working and it still does not work so I know for a fact it has to do with the logic board and not the speakers or components. Video does not work/YouTube due to sound to working. Inrestored the device 3 times as well. Any ever had this happen and what's is a possible fix on the logic board?

Answered! View the answer I have this problem too

Is this a good question?

Audio ic would be my best guess

Update (08/25/2017)

Here is a link to iphone 6+ audio ic replacement. But not knowing a hundred percent certain if that's your issue or not you may want to look at zxw or schematics for that audio circuit and make sure that there's not a filter, Cap or Another Part on that circuit that is shorted or bad before attempting to change it.

If @teetopp01 is right, and I agree he is, this is a bigger problem, and not recommended for beginners to microsoldering


I am willing to learn, it's not my main phone I enjoy doing this as a hobby and would like to perfect it. Although I never ran into this issue before!
