Audio IC Disease in iPhone 7 and 7plus:

As the iPhone 7's begin to age, the signature problems are starting to emerge. At the top of the list are problems with the iPhone 7 audio system.

You may notice any or all of the following list of symptoms:

Callers can't hear you
Voice memos are greyed out
Sound doesn't record on videos
Siri can't hear you
You hear static on calls
Speakerphone doesn't work
The underlying problem: C12 pad at audio ic

All of these are symptoms of the same underlying logic board problem---a thin metal pad that the audio chip is attached to has separated from the logic board.
Interestingly, it is always the SAME PAD--the C12 pad. This part of the logic board is a spot that brokers the connection of the master clock line to the audio integrated circuit (IC) chip. C12 loosens and lifts from the board like peeling nail polish, triggering the symptoms above.
